A contrast medium for medical ultrasonography is a formulation of encapsulated gaseous microbubbles to increase echogenicity of blood, discovered by Dr Raymond Gramiak in 1968 and named contrast-enhanced ultrasound. This contrast medical imaging modality is clinically used throughout the world, in particular for echocardiography in the United States and for ultrasound radiology in Europe and Asia.

Ultrasound has been used in Medicine for close to half a century and its safety has been studied for almost the same period of time. In 1992, the US FDA first allowed the use of ultrasound at a frequency of 1.6 MHz in a toothbrush. In 1993, the American Institute of Ultrasound in Medicine (AIUM), in conjunction with the National Electrical Manufacturers Association (NEMA) developed the Output Display Standard (ODS), including the thermal index and mechanical index which have been incorporated into the FDA’s new regulations. These regulations limit the power output of these devices to a level low enough to avoid raising surrounding tissue temperature by more than 1 °C.

Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasound imaging or sonography is often used in medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws. Industrially, ultrasound is used for cleaning, mixing, and accelerating chemical processes. Animals such as bats and porpoises use ultrasound for locating prey and obstacles. Scientists are also studying ultrasound using graphene diaphragms as a method of communication.

The use of ultrasound in medicine was pioneered by Donald, first at Glasgow Royal Maternity Hospital and subsequently at Glasgow's new maternity hospital, the Queen Mother's Hospital (QMH), which opened in 1964. Developments in ultrasound complemented Whitfield's own research interests in fetal medicine but was still regarded with scepticism in some quarters. Whitfield had more success in gaining acceptance for obstetric ultrasound than Donald himself, who was sometimes viewed as an obsessive eccentric. As he recalled, "an honorary attachment with Professor Donald in Glasgow in 1964 had convinced me that obstetric ultrasound did have a future, but later in that year in America I was told it was just a dream of a mad, red-headed Scotsman, so I should forget it! I was told confidentially, nothing, no good will come of it, but of course that was wrong".

Ultrasound in Medicine and Biology is a monthly peer-reviewed medical journal published by Elsevier on behalf of the World Federation for Ultrasound in Medicine and Biology. It covers ultrasound technology in clinical diagnostic, interventional and therapeutic applications, including the physics, engineering, and technology of ultrasound in medicine and biology. It was established in 1973. The editor-in-chief is Christy K. Holland (University of Cincinnati) since 2006. The founding editor was Denis N. White, who served from 1973 to 1992 and was succeeded by Peter N. T. Wells.

The Advanced Diagnostic Ultrasound in Microgravity Study is funded by the National Space Biomedical Research Institute and involves the use of ultrasound among Astronauts including former ISS Commanders Leroy Chiao and Gennady Padalka who are guided by remote experts to diagnose and potentially treat hundreds of medical conditions in space. This study has a widespread impact and has been extended to cover professional and Olympic sports injuries as well as medical students. It is anticipated that remote guided ultrasound will have application on Earth in emergency and rural care situations. Findings from this study were submitted for publication to the journal Radiology aboard the International Space Station; the first article submitted in space.

In 1977, Freeman became the first hospital to use ultrasound in diagnostic services and nuclear medicine.

The use of ultrasonography in medicine soon followed in different locations around the world. In the mid-1950s more research was undertaken by Professor Ian Donald et al., in Glasgow, which advanced the practical technology and applications of ultrasound. In 1963, in France, Léandre Pourcelot started on his thesis, which was presented in 1964, and used pulsed Doppler for blood flow calculation as its subject. This was followed up by Peronneau in 1969. Dr. Gene Strandness and the bio-engineering group at the University of Washington who conducted research on Doppler ultrasound as a diagnostic tool for vascular disease, published their first work in 1967. The first report published about the venous system appeared around 1967–1968.

Sonography (ultrasonography) is widely used in medicine. It is possible to perform both diagnosis and therapeutic procedures, using ultrasound to guide interventional procedures such as biopsies or drainage of fluid collections. Sonographers are medical professionals who perform scans which are then traditionally interpreted by radiologists, physicians who specialize in the application and interpretation of a wide variety of medical imaging modalities, or by cardiologists in the case of cardiac ultrasonography (echocardiography). Increasingly, clinicians (physicians and other healthcare professionals who provide direct patient care) are using ultrasound in office and hospital practice (Point of Care Ultrasound).

Sackler began his career practicing medicine, where he specialized in biological psychiatry. In the early 1940s he joined medical advertising agency William Douglas McAdams Inc. From 1949 - 1954, he served as a research director at Creedmoor Institute for Psychobiological Studies. Sackler collaborated on 140 papers based on neuroendocrinology, psychiatry, and experimental medicine. He was the first doctor to use ultrasound for diagnosis, identified histamine as a hormone, and advocated for its use as an alternative to electroconvulsive therapy. He is also credited with helping to racially integrate New York City's first blood banks.

From the 1960s commercially available systems were introduced. Soon, other advances in electronics and piezoelectric materials enabled further improvements which meant that ultrasound was quickly adopted for use in medicine due to its rapid, accurate diagnostic capabilities which offered the possibility of prompt treatment. Alongside the improving imaging technology, acoustic Doppler velocimetry and medical ultrasonography color Doppler were developed, which have had a significant impact on many specialties, including radiology, obstetrics, gynecology, angiology and cardiology, and have provided even greater scope for ultrasound investigations. Since 1970, real-time scanners and pulsed Doppler, have enabled the use of ultrasound to study the function of the venous system. The first demonstration of color Doppler was achieved by Geoff Stevenson.
Further progress in the 1970s was made with the arrival of the microchip, and the ensuing exponential increase in processing power has meant the development of fast and powerful systems. These systems involving digital beamforming and greater signal enhancement, have introduced new methods of interpreting and displaying data.
