GYNECOLOGIC PROCEDURES


GYNECOLOGIC ULTRASOUND


This imaging modality uses low-energy, high-frequency sound waves.


Transvaginal    transducers are utilized    for lower   pelvic  masses, producing
high-resolution images that are not influenced by the thickness of the
maternal abdominal wall.
Transabdominal transducers provide images throughout the entire pelvis as
well as abdomen.
Ultrasound works best when adjacent tissues have differing echodensities,
particularly fluid/tissue interfaces.
