A Basic Guide to Ultrasounds

Last updated 10 months ago

Ultrasound, also known as sonography, is one of many medical imaging modalities that have revolutionized modern diagnostic and treatment methods. Using high frequency sound waves, this technology has the ability to create images of the organs and other tissues within the body. Ultrasound imaging is very versatile and can be used to evaluate a variety of medical conditions, including:

Blood flow through the body’s veins
Cardiovascular disease and heart health
Abnormalities in the reproductive organs and prostate
Injuries or abnormalities of the muscles or tendons
The status of fetal development during pregnancy

Following the same general principles as the sonar used by bats, dolphins and submarines, ultrasound technology uses a specialized transducer to emit sound into the body. The sound is bounced back by various tissues, and these “echoes” are picked up by the transducer and used to formulate a precise image. Because no radiation is used for the procedure, it has no direct risks to patient or physician health. Ultrasound is also completely noninvasive and pain-free.

Like other medical imaging technologies, ultrasound does have its unique benefits and limitations. Because sound waves do not travel well through bone or air, ultrasound is not typically used to image tissues that contain gases or that are behind bony structures. To view these tissues, a physician may recommend other diagnostic imaging modalities, such as x-ray or magnetic resonance imaging (MRI), that are better equipped to form more accurate images of those areas.
