What is a Transvaginal Ultrasound?
A transvaginal-ultrasound, also called transvaginal sonogram (TVS), is an ultrasound that uses an internal probe, or transducer, that enters the vaginal cavity. Either a radiology technician or physician performs the test, and a radiologist interprets the results.The transvaginal ultrasound uses a small, wand-like transducer, or probe, which is inserted into the vagina. The probe emits high-frequency sound waves, which are not audible by humans. These sound waves painlessly bounce off the structures in its path. The returning echo wave is picked up by the probe. This information is fed into an attached computer that then creates an image, or sonogram, on a screen.
