Normal pelvic anatomy using transvaginal scanning

The fine spatial and contrast resolution accorded by TVS provides us with the opportunity to see the uterus, ovary, and larger pelvic vessels with detail and accuracy. Other structures may also be visualized but not with the same finesse, regularity, or attention. Transvaginal color Doppler imaging and pulsed waveform analysis capabilities now provide us with the opportunity of distinguishing vascular and nonvascular structures, and gives us the ability to determine the normal and abnormal flow characteristics of pelvic viscera. Improvements in TVS technology will undoubtedly expand our future capabilities and applications.
