Diagnostic ultrasound is a rapidly developing imaging technology which is widely used in both industrialized and developing countries. Since its introduction in the 1960s, ultrasound has found widespread application in anatomical imaging, blood-flow measurement, and evaluation of physiology in almost all aspects of medicine. As ultrasound instruments have become smaller, less expensive, and easier to use, diagnostic ultrasound has become increasingly popular among a wide variety of physicians. Ultrasound imaging technique has replaced or complemented a large number of radiographic and nuclear medicine procedures and has opened new areas of diagnostic investigation. Ultrasound is considered as the primary imaging modality for the detection of most gynaecological, hepatic, biliary, pancreatic, splenic, and renal diseases and for examination of the scrotal contents, bladder, and prostate. In many developing countries, diagnostic ultrasound may find an important application as an epidemiological screening and diagnostic procedure for a number of parasitic diseases, such as amoebiasis, schistosomiasis, and echinococcosis.
