Ultrasound, commonly called Sonography or Medical Sonography, is a diagnostic medical procedure that uses high frequency sound waves (ultrasound) to produce dynamic visual images of organs, tissues, or blood flow inside the body. This type of procedure is often referred to as a sonogram or ultrasound scan.
Sonography can be used to examine many parts of the body, such as the abdomen, breasts, obstetrics & gynecology, prostate, heart, and blood vessels.
More and more, sonography is being used in the detection and treatment of heart disease and vascular disease that can lead to a stroke. It is also used to guide fine-needle tissue biopsies. Unlike X-rays, sonography is a radiation-free imaging modality.
The profession requires judgment, critical thinking, and the ability to provide appropriate health-care services. Sonographers are highly skilled professionals qualified by technological education to provide patient services using diagnostic ultrasound under the supervision of a doctor of medicine or osteopathy.
The sonographer may provide this service in a variety of medical settings where the physician is responsible for the use and interpretation of ultrasound procedures. Sonographers assist physicians in gathering sonographic data necessary to reach diagnostic decisions.
