Transvaginal ultrasound (TV/US) has the advantageTransvaginal ultrasound (TV/US) has the advantage over the abdominal US in gynecology , becauseover the abdominal US in gynecology , because
the close proximity of the intravaginal trancducerthe close proximity of the intravaginal trancducer allows for high – frequency scanning and betterallows for high – frequency scanning and better
