How often should I go for gynaecological imaging?

In our latest article, Professor Nazar Amso, a revered consultant obstetrician and gynaecologist, provides us with a detailed account on what gynaecological imaging involves, and which specific tests are generally performed in gynaecological imaging.

What exactly does gynaecological imaging entail?

Gynaecological imaging attempts to examine a part of the body with a specific test that gives additional information beyond the naked eye. Such tests may be carried out in the clinic during a consultation such as ultrasound and colposcopy, or in a dedicated setting such as a radiology department for CT and MRI scans. Procedures such as hysteroscopy or laparoscopy can be carried out in a dedicated treatment room or operating theatre, respectively.


What tests are normally carried out in the branch of gynaecological imaging?

Transabdominal scanning (TAS) and transvaginal scanning (TVS) are the most widely available techniques, and, in the past few years, TVS has taken prominence in the establishment of gynaecology one-stop clinics.


The vast majority of practitioners carry out 2-Dimensional (2D) scanning, whereby an ultrasound probe is placed over the lower abdomen or introduced into the vagina to examine the pelvic structures. TAS requires filling the bladder while TVS is done with an empty bladder.


The pelvis is examined systematically to determine the normality of the uterus, thickness of the lining of the womb, the appearance of the ovaries, as well as their activity during the menstrual cycle. 3-Dimensional (3D) scanning is a more sophisticated technique that allows the operator to obtain more detailed information on the uterine shape and the presence or not of uterine abnormalities such as a septum or polyps. It also allows better determination of the margin between the lining of the womb and muscle layer, which is particularly useful in adenomyosis.


Ultrasound-guided procedures, e.g., saline infusion sonography (SIS) or hystero-contrast-sonography (HyCoSy) are procedures that are performed in the office, and involve the introduction of normal saline or a contrast solution into the cavity to get more information on any intracavity lesion(s) in the former and assess tubal patency in the latter.


MRI is another excellent technique that is not operator-dependent, as is the case with ultrasound, and it allows us to see the different tissue planes of the body in greater detail. It requires the patient to attend the radiology department and lie down on a table where the MRI machine scans the body. The consultant radiologist interprets the images.


CT scanning is another useful technique commonly used in women with cancer or inflammatory conditions. It also requires the patient to attend the radiology department and the CT machine scans the body. The consultant radiologist interprets the images.


Colposcopy and vulvoscopy are techniques whereby the cervix or vulva are examined with a magnifying device (colposcope) that examines the surface in great detail and allows a targeted tissue biopsy to be taken and extracted.


Hysteroscopy is a technique that allows a thorough examination to take place of the inside of the uterine cavity with a narrow telescope and very often complements TVS. In many instances, when carried out as a diagnostic procedure, a hysteroscopy does not require general anaesthetic and is done in an office environment. However, in cases when a polyp or fibroid requires removal, general anaesthetic and admission to the hospital for a few hours are very likely needed.


Finally, laparoscopy is a technique that allows examination of the inside of the abdominal cavity with a narrow telescope and is always done under general anaesthetic. It is done for diagnostic and therapeutic purposes and requires admission to the hospital for a few hours.


What are the most common gynaecological emergencies where imaging is helpful?

The most common gynaecological emergencies where imaging is helpful include vaginal bleeding and pain in early pregnancy, (where miscarriage is the primary concern), acute severe pelvic pain, and heavy menstrual bleeding and flooding, which requires the woman to attend the hospital as an emergency.


How often should women go for gynaecological imaging?

There is no rule regarding how often a woman should have an imaging test, especially if she is well and healthy and without symptoms. However, many women in the perimenopause state decide, for their peace of mind, to have a TVS once a year to check their uterus and ovaries.


In these cases, there is no clinical indication, but simply personal choice. In situations where there is a known small or medium-sized cyst in the ovary that has been investigated and judged not to be serious, and the patient doesn’t wish to have surgery, a scan may be repeated at regular intervals such as every six to twelve months to ensure that it is not growing further.

Obstetrics & gynaecology

Professor Nazar Amso is a leading consultant obstetrician and gynaecologist currently practicing at Cardiff-based Oak Tree Clinic and Spire Cardiff Hospital, as well as St Joseph's Hospital, Malpas, Newport. He specialises in minimal access hysteroscopic and laparoscopic surgery, fertility investigations, treatments, adolescent gynaecology and joint clinics for paediatric care.

He qualified in 1974 from The College of Medicine at The University of Baghdad, in Iraq. After residency training at a number of teaching hospitals in Baghdad, Professor Amso chose to specialise in obstetrics and gynaecology. He studied at The University of Wales College of Medicine and The University Hospital of Wales, where he has established national and international clinical and research collaborations. 

His professional career journey in the UK began in 1981 and progressed in training posts from West and East Sussex, then later London and Newcastle Upon Tyne. He also undertook research between 1987-1991 at The Royal Free Hospital, London, which culminated in a consultant obstetrician and gynaecologist post at Gateshead.

Professor Amso's clinical practice has since focused on developing new and innovative approaches to service delivery for benign gynaecology. He set up the first ultrasound-based one-stop menstrual disorders clinic in Wales and introduced new treatments such as non-surgical interventions for fibroids and balloon endometrial ablation for menorrhagia. Ultrasound has been the passion of Professor Amso ever since he was a junior trainee. He pioneered the ovarian cancer screening trial in Cardiff and undertook many of the advanced scans. He also provided advice and counselling for the trial's volunteers.

Following Professor Amso's retirement from Cardiff University, he shifted his focus to his interest in education and incorporated limited companies to establish educational partnerships with other like-minded organisations and deliver remote/distance learning medical education in skills-focussed specialties for the UK and the rest of the world.
