Gynaecology scans
The introduction of the transvaginal probe allows investigation of the function of the uterus and ovaries, as well as the accurate diagnosis of gynaecological disease prior to surgery. In fact, it often makes surgery unnecessary.
The usual gynaecological scan involves the introduction of a thin probe through the vagina [transvaginal scan (TVS)] for the close examination of the uterus and ovaries. The bladder should be empty, and the examination is not uncomfortable. Occasionally, TVS is not possible (for example, in virgins), and an abdominal scan [transabdominal scan (TAS)] may need to be performed.
Common indications for gynaecological scanning:
- Abnormal periods (heavy or irregular).
- Investigation of infertility.
- Assessment of fibroids.
- Endometriosis.
- Ovarian cysts.
- Post-menopausal bleeding.
- Screening for ovarian cancer.
Apart from the usual grey-scale scanning, colour Doppler studies may give additional information on the nature of cysts and masses.
