Transvaginal Ultrasound (Sonogram)

In a transvaginal ultrasound, an instrument called an ultrasound scanner sends out sound waves and receives echoes as they bounce off the ovaries. These echoes create electronic pictures of the ovaries on a small television screen. Transvaginal ultrasound is done with a wand-shaped scanner that is covered with a latex or latex-free cover and inserted into the vagina. You will feel some pressure from the transducer as it is inserted. A radiologist interprets the pictures and then reports the findings to the doctor.

This test can show any growths on or near your ovaries, although doctors can't tell just from looking at the growths whether they are cancer. Unless you are having a transabdominal ultrasound performed first, you will be instructed not to drink any fluids four hours before the procedure. This procedure is usually performed in a clinic setting or doctor's office.
