Computed Tomography (CT)

Computed tomography is a specialized form of X-ray, resulting in cross-sectional computerized images and occasionally 3-dimensional images of the head or body.

CT is most often used to evaluate acute stroke, pulmonary embolism, hearing loss, and other problems in the sinuses, chest, abdomen, and pelvis. It is also used to assess bony problems in the spine and extremities and facilitate a needle-biopsy procedure.

A state-of-the-art 64-slice CT scanner is available at Thornton Hospital and UCSD Medical Center, Hillcrest. with this powerful and ultrafast machine, physicians can get incredibly clear and detailed images within seconds and patients are exposed to less radiation than with standard technology. This system can perform CT colonography which does not require sedation (unlike colonoscopy).

CT angiography of the coronary arteries can be performed in patients with acute chest pain who may be having a heart attack. A 64-slice CT with an intravenous injection gives comparable information to cardiac catheterization, which requires an arterial puncture in the groin.
