How does an Ultrasound work?

Diagnostic ultrasound, also called sonography or diagnostic medical sonography, is an imaging method that uses high-frequency sound waves to produce images of structures within your body. The images can provide valuable information for diagnosing and treating a variety of diseases and conditions.

Most ultrasound examinations are done using an ultrasound device outside your body, though some involve placing a device inside your body.

What is Ultrasound used for?

Ultrasound is used for several reasons, including:

  • Obstetrics and gynecology: an ultrasound can be used to view the uterus and ovaries to check for common issues such as cysts and lesions. During pregnancy, ultrasounds can also be used to check the health and growth of the fetus.
  • Glandular, tissue, and reproductive health: diagnostic ultrasounds can help visualize problems or growths on the thyroid gland, lumps in breast tissue, and issues with the prostate.
  • Assist in other medical procedures: because they provide real time visual feedback, ultrasounds can be useful for guiding needle positions during biopsies or tumor treatments.
