What is a computed tomography scan used for?

A CT scan can be used to visualize nearly all parts of the body and is used to diagnose disease or injury as well as to plan medical, surgical or radiation treatment.

Is Computed Tomography the same as a CAT scan?

What are CT scans? A CT scan is a form of X-raying that involves a large X-ray machine. CT scans are sometimes called CAT scans.

Is Computed Tomography painful?

CT scanning is painless, noninvasive, and accurate. A major advantage of CT is its ability to image bone, soft tissue, and blood vessels all at the same time. Unlike conventional x-rays, CT scanning provides very detailed images of many types of tissue as well as the lungs, bones, and blood vessels.

When are computed tomography CT scans indicated?

CT scans may be performed to help diagnose tumors, investigate internal bleeding, or check for other internal injuries or damage. CT can also be used for a tissue or fluid biopsy.

What does tomography mean in medical terms?

Medical Definition of tomography : a method of producing a three-dimensional image of the internal structures of a solid object (as the human body) by the observation and recording of the differences in the effects on the passage of waves of energy impinging on those structures. — called also stratigraphy.

How long does a CTA of the heart take?

As the heart beats, the contrast material outlines the vessels, valves and chambers and pictures are taken to identify blockages or narrowed areas in the coronary arteries. The average catheterization procedure lasts about 30 minutes, but the preparation and recovery time add several hours.

Is Computed Tomography Safe?

CT Scanning and Radiation Safety Studies show that the risk of cancer from CT scans is extremely low. Sometimes, your health condition will require an imaging exam that uses ionizing radiation. If you have concerns, talk to your doctor about the need for and importance of the exam.

Which radiation is used in computed tomography scan?

CT imaging involves the use of x-rays, which are a form of ionizing radiation. Exposure to ionizing radiation is known to increase the risk of cancer.
