Transvaginal color Doppler ultrasonography in reproductive gynecology.

Transvaginal color Doppler sonography (TVSCD) is one of the most important recent developments in gynecology. TVSCD provides relevant information on uterine and ovarian blood flow and aids in the identification of pregnancy viability as well as the early diagnosis of ectopic pregnancy. TVSCD also facilitates differential diagnosis of benign and malignant pelvic pathology.
