Report of the Ultrasonography Task Force

Council on Scientific Affairs

JAMA. 1991;265(9):1155-1159.

Abstract
Over the past 20 years, there has been a dramatic increase in the use of ultrasonography as an imaging modality. The introduction of real-time ultrasonography and Doppler units for the measurement of blood flow in the 1970s, recent advances in transducer design, signal processing, and miniaturization of electronics, along with the lack of radiation exposure, have been primarily responsible for the increased use of ultrasound. However, although ultrasonography can provide diagnostic information safely and easily, interpretation of the information requires an understanding of the physics behind ultrasound, how that physics is translated into ultrasound instrumentation, recognition of artifacts that are associated with the various types of ultrasonography, and identification of these artifacts in specific anatomic locations.
