A Pelvic Ultrasound Scan aims to visualise the organs of the pelvis, including the uterus, ovaries, fallopian tubes and bladder.
An Ultrasound Scan is a method of obtaining images of almost any part of the body. It works on the principle of reflection of high-frequency sound waves at interfaces between tissues of different density. It does not use any radiation and is safe for children and pregnant women.
Pelvic Ultrasound Scan can be performed in two ways: Trans-Abdominal Scan is performed in much the same way as an Ultrasound Scan of the Abdomen. A full bladder is essential. You will be required to drink a litre of water approximately 30 to 60 minutes before your scan, change into a hospital gown, and not pass urine until after the scan. The ultrasound probe is pushed against your lower abdominal wall and looks down into the pelvis. Trans-Vaginal (TV) Scan is performed with an empty bladder, usually following a trans-abdominal scan. It uses a thin probe inserted into the vagina. This allows more detailed information to be obtained by having the probe closer to the pelvic organs.
Ultrasound scanning is performed by a specifically trained Sonographer, who uses the ultrasound machine to obtain images on a screen, usually in black and white. These images are stored electronically and can be printed out for viewing, but most of the information is gained by an experienced sonographer during the actual examination.
Pelvic Ultrasound Scans are routinely performed in pregnancy in order to confirm gestation, to screen for risk of congenital abnormalities in the first trimester, and to screen for anatomical abnormalities later in pregnancy. Ultrasound of the pelvis is also a common test for abdominal or pelvic pain in women, and may be useful to investigate for ovarian cysts, endometriosis, and abnormalities of the uterus.
Pelvic Ultrasound results are usually forwarded to your doctor for interpretation and explanation. The Sonographer may communicate some of the scan findings during the actual examination.
