by Dr. Donald L. King The past decade has seen the ascent of ultrasonography to a preeminent position as a diagnostic imaging modality for obstetrics and gynecology. It can be stated without qualification that modern obstetrics and gynecology cannot be practiced without the use of diagnostic ultrasound, and in particular, the use of ultrasonograยญ phy. Ultrasonography quickly and safely provides detailed, highยญ resolution images of the pelvic organs and gravid uterus. The quality and quantity of diagnostic information obtained by ultraยญ sonography far exceeds anything previously available and has had a revolutionary impact on the management of patients. Highยญ resolution static images permit the intrauterine diagnosis of fetal growth retardation and fetal abnormalities. In addition to tradiยญ tional images, newer dynamic imaging techniques allow observaยญ tion of fetal motion, cardiac pulsation, and respiratory efforts. The use of ultrasonography for guidance has greatly augmented the safety and utility of amniocentesis. One of the great virtues of diagnostic ultrasound has been its apparent safety. At present energy levels, diagnostic ultrasound appears to be without any injurious effect. Although all the availaยญ ble evidence suggests that it is a very safe modality and that the benefit to risk ratio is very high, the actual safety margin for its use Vll as yet remains unknown. As a consequence, practitioners are urged to limit its use only to those situations in which genuine clinical indicaยญ tions exist and real benefit to the patient is likely to result
