TVS (Transvaginal Sonography) is a type of pelvic ultrasound that provides a close and detailed view of a woman’s reproductive organs, including the uterus, ovaries, fallopian tubes, cervix, and endometrium. Unlike a standard abdominal ultrasound, TVS is performed internally by inserting a thin, lubricated transducer (probe) into the vagina.
This scan is commonly used to evaluate issues such as irregular periods, pelvic pain, abnormal bleeding, infertility, ovarian cysts, fibroids, and early pregnancy complications. It provides clearer and more accurate images of pelvic structures, especially in early pregnancy or in women who are overweight.
TVS is safe, quick, and typically painless, although it may cause mild discomfort. It takes about 15 to 20 minutes, and no radiation is involved. The scan is often done with an empty bladder, unlike abdominal scans that require a full bladder.
Doctors frequently use TVS for early pregnancy detection, to confirm fetal heartbeat, or to rule out ectopic pregnancy. It is also useful in diagnosing conditions like PCOS, endometriosis, and uterine abnormalities.
