This test is an ultrasound which is primarily performed on women. We image the uterus, ovaries and the surrounding area. Abnormalities, such as ovarian cysts and tumors, free fluid and uterine fibroids are the primary findings. This test lasts approximately 15 to 30 minutes if the patient’s bladder is fully distended. The preparation for a full bladder is 32 to 62 ounces of any fluid one hour prior to the exam. Occasionally overlying bowel gas obscures our view and a second ultrasound procedure, called a transvaginal scan, may be necessary. This part requires an empty bladder and a probe placed internally into the vaginal cavity. This procedure may take an additional 15 minutes.
