Endovaginal and translabial ultrasound in pregnancy.
Endovaginal sonography provides earlier and enhanced visualization of the gestational sac and its contents than does transvesical sonography. This paper discusses the role of endovaginal sonography in common first trimester diagnostic problems, including pregnancy dating, first trimester pregnancy loss, ectopic pregnancy, and early diagnosis of fetal anomalies, and reviews the use of endovaginal color flow Doppler in the diagnosis of ectopic pregnancy. A brief discussion of the role of endovaginal and translabial sonography in the second and third trimesters is included.
