Ultrasonography

Ultrasonography

Ultrasonography uses high-frequency sound (ultrasound) waves to produce images of internal organs and other tissues. A device called a transducer converts electrical current into sound waves, which are sent into the body’s tissues.

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.

A fetal ultrasound (sonogram) is an imaging technique that uses sound waves to produce images of a fetus in the uterus. Fetal ultrasound images can help your health care provider evaluate your baby’s growth and development and monitor your pregnancy.

Types of Ultrasound

  • Endoscopic ultrasound.
  • Doppler ultrasound.
  • Color Doppler.
  • Duplex ultrasound.Triplex ultrasound (color-flow imaging)
  • Transvaginal ultrasound.

The diagnostic ultrasound, also known as the sonography test, uses the principle of “Doppler effect” or echoes to convert the reflected sound energy into images.

Often, the terms sonogram and ultrasound are used interchangeably. However, there’s a difference between the two: An ultrasound is a tool used to take a picture.. Sonography is the use of an ultrasound tool for diagnostic purposes.

Careful attention to the bowel when performing a pelvic US may allow the sonographer to diagnose GI pelvic diseases such as appendicitis, diverticulitis, colitis, bowel obstruction, mesenteric adenitis, epiploic appendicitis, Crohn disease, and even GI malignancy.
