CT Scan


Important Things to Know About CT

CT uses X-rays and computer technology to create images of bones, organs, and blood vessels. CT images help doctors diagnose conditions and determine treatment. CT images can help assess internal trauma, guide procedures and diagnose cancer or fractures.

CT is painless and usually lasts only a few minutes. Some patients require an intravenous or oral contrast agent to improve image quality.
