The transvaginal ultrasound examines the uterus and ovaries, and looks for any abnormalities of the female reproductive tract. A scan is advisable if one or more applies to you:

• Abnormal uterine bleeding
• Unexplained abdominal pain
• Family history of ovarian cancer
• To determine whether a pregnancy is normal or ectopic, and that the placenta and uterus are normal
• Excess facial hair or previous diagnosis of polycystic ovary syndrome(PCOS)

If you are post menopausal, the following may also be a consideration:

• To check for hyperplasia (overgrowth in the thickness of the uterine lining) or cancer of the endometrium (lining of the uterus)
• To determine whether an abnormal area (such as an endometrial polyp or uterine fibroid) is present in the uterus before further, more invasive investigations.

The transvaginal ultrasound scan can visualise all of the female reproductive organs in extreme detail. As such it can detect many abnormalities of the ovaries or uterus as well as assessing the fetus and placenta.

A small, smooth ultrasound probe, about the size of an index finger, is inserted into the vagina. The transvaginal ultrasound is far more accurate and sensitive than an external abdominal or pelvic scan, as the probe is much closer to the reproductive organs. For the ultrasound itself, you will asked to remove your lower garments and your underwear and lie on a couch. A blanket or sheet will be provided for your comfort and modesty. Although the ultrasound probe may feel a little uncomfortable when first inserted into the vagina, it should not be painful in any way. The examination takes just 10 minutes to complete. Our female radiographer is a specialist in this procedure and is used by many gynaecologists.
