transvaginal ultrasound

Pronunciation: (tranz-VA-jih-nul UL-truh-sownd)

A procedure used to examine the vagina, uterus, fallopian tubes, ovaries, and bladder. An instrument is inserted into the vagina that causes sound waves to bounce off organs inside the pelvis. These sound waves create echoes that are sent to a computer, which creates a picture called a sonogram. Also called transvaginal sonography and TVS.

Caption: Transvaginal ultrasound. An ultrasound probe connected to a computer is inserted into the vagina and is gently moved to show different organs. The probe bounces sound waves off internal organs and tissues to make echoes that form a sonogram (computer picture).
