Sonography is a versatile diagnostic imaging modality which uses acoustical energy. In the pediatric patient, it can be used in several areas of the body, particularly within the abdomen and pelvis.

Over the last several years, the use of sonography for the evaluation of pediatric disorders has become more widespread for several reasons. These include the non-ionizing character of sonography relative to the radiographic techniques and the enhanced soft tissue detail now afforded by most real-time ultrasound scanners.

The increased use and availability of real-time scanners has also contributed to more extensive use of sonography. Since children have very little perivisceral fat, they are almost ideal subjects for ultrasound scanning because high-frequency transducers which afford the best possible resolution can be used. The lack of irradiation allows repeat examinations to be performed without fear of untoward bioeffects due to radiation.

The role of sonography in the evaluation of pediatric gynecologic disorders will no doubt continue to expand, particularly as more pediatricians, gynecologists and radiologists become more familiar with its applications in pediatric gynecology.
