TVU
Also written as: TVU — transvaginal ultrasound
Transvaginal ultrasound, an imaging technique using a probe inserted into the vagina to visualize pelvic organs.
Full Definition
Transvaginal ultrasound (TVU) is a diagnostic imaging procedure that uses high-frequency sound waves transmitted through a specially designed transducer inserted into the vagina to create detailed images of the female reproductive organs. This technique provides superior visualization of the uterus, ovaries, fallopian tubes, and surrounding structures compared to transabdominal ultrasound, particularly in early pregnancy or when evaluating pelvic masses. TVU is commonly used for pregnancy confirmation and dating, evaluation of pelvic pain, assessment of abnormal bleeding, monitoring ovarian cysts, and guiding certain procedures such as follicle aspiration during fertility treatments.
