Computed Tomography (CT) scans, also known as CAT (Computed Axial Tomography) scans, produce multiple cross-sectional images of the body by using special X-rays and computer enhancements. This technology creates an image many times more sensitive and detailed than a simple X-ray can produce. The detailed assessment gives your doctor information to help diagnose your condition.
Our CT equipment is calibrated as required to ensure that As Low As Reasonably Achievable (ALARA) radiation dose is delivered to the patients, while maintaining high-quality images. Radiation dose is carefully monitored on all CT exams.
CT images can be used to detect and characterize sites of suspected cancer, infection, or inflammation. A CT scan can be used to study all parts of the body. It can display complex anatomical relationships in the head, neck, spine, and extremities. CT can provide an analysis of vascular structures to find sites of narrowing, blockage, or aneurysm formation.
An X-ray tube rotates around your body and examines it from many angles. The images are transferred to a computer, and a detailed two-dimensional cross-section, or “slice,” of the body is generated. These slices can then be processed further to generate 3-D images viewable from many different angles.
In some cases, you may be given an intravenous contrast agent to optimize the results and show the anatomy of vascular structures more clearly. For information about preparing for a CT scan, see Preparing for Your Exam
