We sat down with QUFW’s Dr. Carol Portmann to learn more about her journey as an obstetrics and gynaecology specialist, her commitment to helping women get the best pregnancy outcomes, her thoughts on medical technology, and more.
Dr. Carol Portmann is a Queensland-trained doctor, obstetrician, and maternal fetal medicine specialist with more than 20 years’ experience.
Engaging in conversation with Dr. Carol Portmann is as interesting as it is inspiring.
Whether it’s hearing about her lifelong interest in obstetrics and gynaecology, the way she masterfully combines empathy with medical advice, or her passion for cooking and travel, Dr. Portmann’s skill as a conversationalist leaves nothing to the imagination as to how, and why, she has achieved so much in her career.
“From the earliest time that I can remember, I always felt that I was going to go somewhere in healthcare, as a doctor, nurse, or one of those roles,” she says.
“I was lucky enough to get into med school, which I did locally here in Queensland.”
Dr. Portmann was attracted to obstetrics early in her career. For the most part, she was drawn to the natural positives of pregnancy and childbirth.
“In this space, there are generally happy endings, and it’s all about making that happen safely.”
“It’s about guiding a natural process,” she explains.
Dr. Portmann pursued a Diploma of Obstetrics in New South Wales, which solidified her interest in the field. Upon completion of this qualification, she returned to Queensland to take up a position at the Mater Mothers Hospital in Brisbane.
Here, her career was greatly influenced by the late Professor Fung Yee Chan.
“During my time at the Mater, I went to many meetings where Professor Fung Yee Chan would show ultrasound pictures of babies with various sorts of conditions,” she explains.
“And I looked up at that screen and was fascinated by what she was doing.”
“I had this strong motivation to learn obstetric ultrasound and how to identify babies with problems.”
Dr. Portmann’s pursuit of this field took her overseas to University College London, in the United Kingdom, where she completed a master’s degree in prenatal genetics and fetal medicine.
Her research, which focused on blood clotting disorders and their implications on pregnancy, advanced her expertise in specialised areas of maternal and fetal health.
“I got a chance to spend time processing blood tests and interviewing people with adverse pregnancy outcomes and putting it all together for a master’s research project.”
“It was fascinating,” she explains.
Upon returning to Australia, Dr. Portmann continued her work in Brisbane. She played a pivotal role in developing the Maternal Fetal Medicine (MFM) department at the Royal Brisbane and Women’s Hospital, and later joined the QUFW team where she practises today.
Reflecting on positivity, but also realism
Dr. Portmann describes her work as, for the most part, joyous. The majority of the pregnancies she sees result in positive outcomes.
However, she also comments on the statistical realism that not all pregnancies unfold as planned, and the importance of delivering advice with empathy when complications arise.
“There’s a lot involved in a complicated high-risk pregnancy, which is what maternal fetal medicine is all about,” she says.
“It’s trying to get the best outcome using your medical skills, but also trying to provide positive and emotional support.”
Early in a complicated pregnancy, she might discuss potential complications. However, through vigilant care and management, she often sees these pregnancies result in the birth of healthy babies, surpassing initial expectations.
“Sometimes, early on, you’ll see things where you’ve got to talk to someone about possibilities.”
“However, you also support them through the process with the view to doing the best you can for a good outcome,” she explains.
“And then as you guide this person through, with their tiny little baby, you get to the end and this little baby is born happier and healthier than you thought they might be, which is fantastic.”
The two sides to technology
Dr. Portmann also explains how developments in imaging technology have dramatically enhanced the ability to identify at-risk pregnancies. This progression has enabled better management of pregnancy complications, and has improved outcomes for both mothers and their babies.
However, for Dr. Portmann, technology can be a double-edged sword. While it brings enhanced capabilities for early diagnosis, it also introduces new challenges, such as the potential for increased patient anxiety over findings that might have uncertain implications.
“Of course, the downside to cutting-edge technology is that we are now finding things that we don’t necessarily know what their significance is.”
“So there’s always a downside to the technology when we identify things that could be an issue, but we don’t really know.”
“Technology is great, but it has the potential to create more anxiety.”
Dr. Portmann also emphasises the limitations of ultrasound imaging. She stresses that while ultrasound is a powerful tool for assessing fetal health, it does not reveal everything and should not be expected to predict all potential issues.
“You’re not going to see everything on an ultrasound about a baby’s wellbeing,” she says.
“And that also includes gynaecology ultrasound.” “You’re not going to identify everything. Not all forms of endometriosis or early reproductive cancers can be excluded.”
On adverse outcomes
Dr. Portmann touches on the ethical dilemmas encountered when potential adverse pregnancy outcomes are found. She discusses the delicate process of counselling parents through decisions about pregnancy continuation, or even termination, in cases where prognoses are uncertain. These situations demand a high degree of sensitivity and ethical consideration, as some choices are profoundly personal and impactful.
She also prioritises starting consultations positively but remaining committed to honesty, especially when the findings are serious. Her approach makes sure that patients are not only well-informed but also supported throughout their journey.
“If I see something that is definitive and serious, I will say what it means and the potential significance and what we need to do.”
“It’s about being honest when we have definitive information, but then when we see something that has some significance but is not necessarily severe, I will begin with positivity and say, look, we found something, but it doesn’t necessarily mean anything bad.”
“I’ll then explain that we need to do further work to just monitor or identify any additional issues.”
The benefits of NIPT
Dr. Portmann explains how non-invasive prenatal testing (NIPT) has been a positive step forward for both the patient and the medical practitioner. NIPT allows for more accurate and sensitive detection of potential issues in fetuses, reducing the need for more invasive procedures like amniocentesis.
“NIPT allows us to identify the babies at risk of problems with greater sensitivity and accuracy, without having to rely on invasive procedures that could put mother and baby at risk,” she says.
This advancement, coupled with improved genetic screening, enables the detection of conditions like cystic fibrosis beyond what ultrasound can reveal, enhancing prenatal care and parental preparedness.
Inspiring the next generation
Dr. Portmann plays a significant role in training the next generation of fetal maternal doctors. And surprisingly, the mentoring advice she has for medical students and young doctors is non-medical.
She stresses the importance of retaining humanity and empathy, reminding medical practitioners that both they and their patients are people first, a perspective that enriches the patient-doctor relationship and enhances care quality.
“Don’t make everything about science,” she says.
“They are people, you’re a person, your patient is a person.”
“Make sure that you retain your humanity on your journey in the medical field.”
On her role at QUFW
Dr. Portmann doesn’t hide her passion for QUFW. Her message to patients and referring general practitioners is clear: the service provided at QUFW is more than just diagnostics; it’s about comprehensive care and support. And it’s about the bigger picture.
This philosophy is central to Dr. Portmann’s practice, and is indicative of her broader approach to healthcare, which prioritises patient wellbeing and informed, supportive care.
“The service that we provide at QUFW is all about counselling, alongside imaging.”
“We don’t just send you away with your scan, and something that you might not know about.”
“We make sure that you’re informed if something is different to usual.”
“And at QUFW we have very, very experienced sonographers and doctors to assist if anything is happening, and to reassure you when we feel that everything is great,” she says.
Career and personal life reflections
Reflecting on her own career, Dr. Portmann acknowledges moments of personal challenge, particularly regarding work-life balance. She candidly shares that there were times when she allowed work to overshadow her personal life, leading to stress and burnout.
This experience taught her the value of taking time for oneself and maintaining connections with family, insights she wishes she had embraced earlier in her career.
Her interests in cooking and travel highlight her approach to maintaining a well-rounded life, which helps her manage the stresses associated with her career.
“I like cooking books. I like cooking classes. I like cooking shows,” she beams.
When quizzed on a particular cuisine, Dr. Portmann demonstrates an ambition for cooking that clearly competes with her passion for women’s health.
“I’ll try anything and everything,” she says with a smile.
Dr. Portmann’s career is a testament to the relationship between medical practice and the timeless values of compassion and ethical integrity. Her dedication to advancing her field while providing empathetic, informed care to her patients highlights her role not just as a medical professional but as a foundation of support for families during one of the most significant times of their lives.
As Dr. Portmann continues her work, her influence extends beyond immediate clinical outcomes. She shapes the practices and attitudes of the future medical cohort through her advocacy, teachings, and exemplary model of care.
Her legacy is one of compassion, innovation, and a commitment to improving the lives of women and their families through excellence in maternal fetal medicine, even if things don’t quite go as planned.

Endometriosis is a common inflammatory condition that occurs when tissue similar to the endometrium (the lining of the uterus) grows in other locations around the body. In many cases, endometriosis causes discomfort, pain, and, occasionally, fertility issues. Endometriosis may affect up to one in seven women.
Despite it being a common condition, endometriosis can be challenging to diagnose due to the variability of its symptoms and their similarity to other conditions. In some women, endometriosis may be present with no symptoms at all.
Endometriosis is a common condition where ‘endometrium’, a type of tissue similar to the inside lining of the uterus, grows in other areas of the body.
Endometriosis is most commonly found around the female reproductive system, including the exterior of the uterus, fallopian tubes, ovaries and other organs within the pelvis.
The physiological effect of endometriosis include:
The presence of endometrial glands and stroma – these are called endometrial implants and usually occur outside of the uterus.
These endometrial implants are considered to be estrogen dependent which can respond to hormonal fluctuations with proliferatory and secretory activity.
Metabolic activity may include the release of cytokines and prostaglandins which can lead to chronic inflammatory response
Characterised by neovascularisation and fibrosis
Fibrosis and adhesions may lead to the physical alteration of the pelvic anatomy
Endometrium continues to behave as it normally would as if it was inside the uterus—it bleeds with each menstrual cycle. However, because it is unable to leave the body, like a normal menstrual cycle, it leads to inflammation and pain.
There are three types of endometriosis:
Superficial Endometriosis (SE): This form of endometriosis involves the growth of endometrial-like tissue on the surface of pelvic organs and structures. These superficial implants are less than 5 mm in depth.
Ovarian Endometriosis (Endometriomas): Endometriomas are cysts filled with dark, reddish-brown blood that form on the ovaries as a result of endometriosis. They can vary in size and may cause the ovaries to adhere to the fallopian tubes or the pelvic wall, leading to pain and affecting fertility.
Deep Infiltrating Endometriosis (DIE): DIE is considered the most severe form of endometriosis. It involves the infiltration of endometrial-like tissue more than 5 mm under the peritoneum, which is the lining of the abdominal cavity. DIE can be located in or around organs such as the bowel, bladder, and, less commonly, the ureters and lungs.
How common is endometriosis?
Recent Australian research suggests that endometriosis may affect as many as one in seven women. Despite its commonality, endometriosis is often underdiagnosed or diagnosed with a delay of up to nine years, sometimes due to the normalisation of menstrual pain or the variability of symptoms among affected individuals.
What are the causes of endometriosis?
There is no single known cause of endometriosis. However research suggest that these factors contribute to the risk of developing endometriosis:
Immune system disorders
Genetic predisposition
Hormonal imbalances
Environmental toxins
What are the symptoms of endometriosis?
Endometriosis presents differently in different people. Symptoms may include:
Pain around the pelvic area
Changes to menstrual frequency, duration, or heaviness
Pain going to the toilet
Infertility
Fatigue
Diarrhoea
Constipation
Bloating
Nausea
How is endometriosis diagnosed?
Your doctor may follow this process for diagnosing endometriosis:
Medical history and symptoms review: Your doctor will ask questions about your symptoms, including how severe they are and how long you’ve had them for. They may also ask about your family’s medical history.
An examination of the pelvic area: Your doctor may conduct a physical examination to check for cysts or scars, or any other physical indicators of endometriosis.
Ultrasound: A transvaginal ultrasound may be ordered to check for cysts associated with endometriosis (endometriomas) and assess the pelvis for evidence of superficial and deep endometriosis. Deep endometriosis may be detected during the ultrasound by specifically trained sonographers. Superficial endometriosis is more common, but not as easily diagnosed by ultrasound. The detection of superficial endometriosis is increasing with better technology and awareness of its subtle features.

Magnetic Resonance Imaging (MRI): An MRI may be performed to check for endometriosis, or be used as an adjunct to a surgical procedure.
Laparoscopy: Still considered to be gold standard, this is a surgical procedure where a camera (laparoscope) is inserted into the pelvis.
Can endometriosis be cured?
There is no definitive cure for endometriosis but it is treatable. It is important to remember that sometimes endometriosis can recur after treatment.
What are the four surgical stages of endometriosis?
Endometriosis is classified into four surgical stages according to the extent, depth, location, and presence of scar tissue and endometriomas (cysts):
Stage I (Minimal): This is the mildest form of endometriosis, featuring light lesions only.
Stage II (Mild): Light lesions and shallow implants on the ovary and pelvic lining with minimal adhesions.
Stage III (Moderate): Deep implants, small cysts on one or both ovaries, and more extensive adhesions.
Stage IV (Severe): Large cysts on one or both ovaries, many deep implants, and thick adhesions. This stage may also involve implants on other organs outside of the pelvic cavity.
How can endometriosis be treated?
Treatment options vary depending on many factors, including the severity of symptoms, a desire for pregnancy, and previous treatment history. Your doctor will advise a treatment plan.
Treatments are mainly aimed at providing relief, reducing and ideally eradicating symptoms to improve your wellbeing. As described by QENDO, there are three main treatment plans that your doctor may recommend to you.
Drug therapy: used to manage endometriosis symptoms and minimise pain. This may include hormone therapies.
Surgery: used to remove the tissue from your body. This has a higher success than drug therapy and can usually be performed at the time of diagnosis. It is important the surgery is performed by a gynaecologist who is familiar with the latest treatment standards for endometriosis.
Alternative treatment: these can include herbal remedies, dietary change, acupuncture, reducing stress and exercise to reduce the pain. Endometriosis is not curable but IS treatable. But remember, sometimes endometriosis can recur after treatment.
Which parts of the body does endometriosis affect?
Endometriosis most commonly impacts the pelvic region. However it can also be found in other locations throughout the body, including but not limited to:
Peritoneum: This is the lining of the abdominal and pelvic cavity, and is the most common location for endometriosis.
Intestines and rectum This leads to symptoms such as painful bowel movements, gastrointestinal pain, and irritable bowel syndrome-like symptoms.

Bladder and urinary tract. This can cause urinary urgency, frequency, and pain during urination.

Diaphragm and lungs: Though rare, endometrial-like tissue can implant in the diaphragm and even the lungs, potentially leading to chest pain and difficulty breathing.
Additionally, endometriosis lesions have been found in even more distant sites, such as the skin, scars (from previous surgeries), and in very rare cases, the brain.
How does endometriosis affect pregnancy?
Endometriosis can influence pregnancy in different ways:
Fertility issues: Endometriosis can create fertility issues in some women. This happens when ovulation and the fertilisation of the egg is interrupted by the presence of endometrial tissue.
Increased risk of complications: Pregnant individuals with endometriosis may have a higher risk of certain complications, such as miscarriage, preterm labour, and placenta previa (where the placenta covers the cervix), compared to those without the condition.
Pain management: For some, pregnancy may lead to a temporary relief of endometriosis symptoms, as menstruation halts and hormonal changes can suppress the condition. However, for others, pregnancy may not alleviate pain, and managing pain without compromising the pregnancy can be challenging.
Obstetric outcomes: Studies suggest that endometriosis may be associated with increased risks of certain obstetric outcomes, including caesarean delivery and postpartum haemorrhage, though more research is needed to fully understand these relationships.
What support is available for people with endometriosis?
Here’s a list of support organisations:
QENDO – A peak organisation providing support to those affected by endometriosis, adenomyosis, PCOS, infertility or pelvic pain, by lobbying for national programs, better healthcare access, support, offering patients tools, services and programs to understand and take control of their health.
Endometriosis Australia – A national charity aiming to increase recognition of endometriosis, provide education programs, and support research.
CHARLI – a health tracking app that can help Australians take control of the diagnosis and management of endometriosis
Pelvic Pain Foundation of Australia – Offers information and support for those suffering from pelvic pain, including endometriosis.
Jean Hailes for Women’s Health – Provides comprehensive information on endometriosis and other women’s health issues, supporting women across Australia.
The Australian Pain Management Association – Offers resources and support for people dealing with pain, including endometriosis-related pain.
Healthdirect Australia – Government-funded service providing trusted health information and advice, including support and resources for endometriosis.
These organisations provide various forms of support, including information on diagnosis and treatment options, access to support networks and communities, and advocacy for better healthcare services for individuals with endometriosis.

Despite endometriosis being a relatively common condition, it is challenging to identify and diagnose. For many years, laparoscopic surgery has been the “gold standard” procedure for definitively identifying endometriosis. However, the use of transvaginal ultrasound by experienced sonographers is emerging as a complementary diagnostic method due to its greater accessibility, lower cost and non surgical approach.
The growing use of TVUS as an endometriosis diagnosis and treatment planning tool also signifies a more important role for sonographers, and specialist practices like QUFW.
Endometriosis is a relatively common inflammatory condition in which cells similar to the endometrium (the lining of the uterus) grow in other locations around the body. While endometriosis is commonly found in and around the pelvis and reproductive organs, it can also grow in other parts of the body, including the bowel, bladder, and other organs.
Common symptoms of endometriosis include abnormal and heavy bleeding, chronic pelvic pain, dysmenorrhea (painful periods) and dyspareunia (pain during or after intercourse) , which can severely affect quality of life and may affect fertility.
Facts about endometriosis:
Recent Australian research suggests that endometriosis may affect as many as one in seven women.
On average, it takes 6.5 years to be diagnosed with endometriosis, during which patients may experience discomfort, pain, and other symptoms.
Endometriosis commonly presents in three different ways:
Superficial endometriosis (SE)
Ovarian endometriosis (endometriomas)
Deep infiltrating endometriosis (DIE)
According to Delsandes et al (2024), endometriosis may lead to further complications including:
Infertility
Bowel obstruction
Renal failure
Recurrent miscarriage
Depression
Higher rates of cancer
Autoimmune conditions
Cardiovascular disease
Endometriosis is a complex condition, which makes its diagnosis and treatment difficult.
A change in the way endometriosis is diagnosed
Laparoscopic surgery has traditionally been the preferred method of diagnosing endometriosis, which involves a surgical procedure to directly visualise and surgically excise lesions. Laparoscopy, like all operations, has potential risk, expense and recovery time.
However a medical imaging process called transvaginal ultrasound (TVUS) is being utilised more effectively by suitably trained sonographers as a method for diagnosing endometriosis.
QUFW Sonographers are skilled and experienced in this process.
What is transvaginal ultrasound (TVUS)?
Transvaginal ultrasound is a diagnostic imaging technique used primarily in gynaecology to obtain detailed images of the female reproductive organs, including the uterus, ovaries, and surrounding areas. This procedure involves the insertion of a small, wand-like device, called a transducer, into the vagina. The transducer emits sound waves that bounce off internal structures, creating echoes that are then converted into images on a monitor.
This method provides higher resolution images than a transabdominal pelvic ultrasound, allowing for more accurate assessment and diagnosis of conditions such as ovarian cysts, uterine fibroids, early stages of pregnancy, and now endometriosis.
The benefits of TVUS
It has been suggested that transvaginal ultrasound can be used as a first-line imaging method for assessing women with suspected endometriosis (Deslandes Et Al 2024). The assessment however, needs to be performed according to well standardised, established protocols. Transvaginal ultrasound is a noninvasive examination that is not only easily accessible, it is inexpensive but allows for preoperative planning in cases that require surgery.
Diagnostic features of endometriosis can be very subtle and it is important that the scan is performed by a skilled sonographer. At QUFW we believe that endometriosis assessment should be part of every routine gynaecological examination.
QUFW has continued interest in continued professional development for our sonographers and has collaborated with leading experts in the field to ensure that we are at the forefront of diagnostic imaging for our patients. Our sonographers have undergone advanced training in detecting endometriosis on ultrasound and follow the International Deep Endometriosis Analysis (IDEA)consensus. This is a four step systematic approach.
The International Deep Endometriosis Analysis (IDEA) consensus has outlined a four-step assessment approach, using TVUS, for the detection of endometriosis:
Assessment Step 1: Uterus and ovaries
Pathology detected:
Adenomyosis

Ultrasound image of an endometrioma in the left ovary
Assessment Step 2: Ovarian mobility and site-specific tenderness
Pathology detected:
Ovarian adhesions
Sites of tenderness which may indicate endometriosis
Assessment of mobility and tenderness of the right ovary by using “probe palpation” via a transvaginal transducer

The growing importance of sonographers
The importance and relevance of transvaginal ultrasound in the detection of endometriosis places sonographers at the forefront of diagnosis.
This is due to:
The nuanced skills required to use ultrasound as a medical imaging modality: Sonographers not only use their advanced imaging skills to detect deep endometriosis, but also rely and utilise dynamic imaging to assess for mobility. Assessing mobility is a limitation of MRI in assessment of endometriosis.
Identification of subtle signs: Sonographers provide expertise in spotting the specific markers of endometriosis, which can be challenging to detect via other non-invasive means.
Patient comfort and communication: Sonographers play a key role in ensuring patient comfort during the procedure.
Collaborative care: Sonographers are vital in the multidisciplinary approach to managing endometriosis, working alongside doctors to tailor patient care.
Potential for future advancements
Emerging techniques and technological developments will continue to advance TVUS as a valuable method for diagnosing endometriosis. Some of these are:
SonoPODography
SonoPODography is an innovative ultrasound-based technique designed for the direct visualisation of superficial endometriosis. This procedure involves the infusion of saline into the pouch of Douglas (POD) via an intrauterine balloon catheter, creating an acoustic window that enhances the ultrasound beam’s ability to visualise the surrounding structures of the pelvis. This method allows for the assessment of the presence or absence of superficial endometriosis using pre-defined features.
Elastography
Elastography is a medical imaging technique that measures the elasticity or stiffness of soft tissue, to detect changes that may indicate disease. It’s often used alongside ultrasound or magnetic resonance imaging (MRI) to add important information about the mechanical properties of tissues. By applying slight pressure and analysing how tissue deforms in response, elastography can help in identifying lesions or abnormalities.
Artificial Intelligence
Artificial Intelligence (AI) can enhance the diagnostic process of endometriosis via transvaginal ultrasound (TVUS) by enabling more accurate analysis of imaging data. AI algorithms can be trained to recognize specific patterns and markers indicative of endometriosis, which may not be easily discernible by the human eye. This can help in identifying the presence and extent of endometriosis with greater precision, supporting sonographers in making more informed decisions and potentially leading to earlier detection and treatment of the condition. However, don’t worry, AI won’t be replacing sonographers any time soon.
This advancement in imaging technology enhances diagnostic precision and also significantly improves the overall management of endometriosis. By offering a less invasive diagnostic option, TVUS minimises patient discomfort and anxiety, allowing for a smoother journey through endometriosis diagnosis and treatment.
