Ultrasound imaging, also called ultrasound scanning or sonography, involves exposing the body to high-frequency sound waves to produce images inside the body. Ultrasound exams do not use ionizing radiation (as used in X-rays). Because ultrasound images are captured in real time, can show the structure and movement of internal organs of the body, as well as blood flowing through blood vessels.

Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions.

An ultrasound of both carotid arteries in the body, which are on either side of the neck and carry blood from the heart to the brain, provides detailed images of these vessels and information about the blood flowing through them.

Doppler ultrasound is a special ultrasound technique that evaluates blood flow through blood vessels, including arteries and veins of the body is important in the abdomen, arms, legs and neck. Read the rest of this entry »

Benefits

* Ultrasound scanning is noninvasive (no needles or injections) and is usually painless.
* Ultrasound is a method that is widely available, easy to use and less expensive than other imaging methods.
* Ultrasound imaging uses no ionizing radiation.
* Ultrasound scanning gives a clear picture of soft tissues that do not show up well on x-ray images
* Ultrasound provides real-time imaging, making it a good tool for guiding minimally invasive procedures such as needle biopsies and needle aspirations.

Risk

* There are no known harmful effects on humans with respect to standard diagnostic ultrasound.
