The future of ultrasonography. Report of the Ultrasonography Task Force. Council on Scientific Affairs, American Medical Association

Future advances in ultrasonography will undoubtedly occur in three major areas: diagnostic capability, instrumentation, and clinical applications. In the area of diagnostic capability, spatial and contrast resolution offer excellent opportunities for improvement. Continued research into tissue characterization is worthwhile, even though efforts to date have been more frustrating than fulfilling. Blood flow studies and new contrast agents are among the more promising areas for future development. New techniques of signal detection, analysis, and display in Doppler imaging may overcome some present limitations, including those in color flow imaging.
