View in Spanish: Transvaginal sonography (en inglés)

Transvaginal sonography (tranz-VA-jih-nul soh-NAH-gruh-fee)
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 ultrasound and TVS.
