Computed tomography (CT) uses special x-ray equipment to obtain anatomical data of the body and performs computer processing of that information. The result is multiple cross-sectional images of the soft tissue, blood vessels and bones. Some of these structures would only appear as indistinct shadows on conventional x-ray.
CT can distinguish between normal and diseased or injured tissue based on changes in size, shape and appearance of the tissue. CT is used to evaluate a wide variety of problems and diseases such as trauma, cardiovascular disease, infectious disease, inflammation and cancer. Early diagnosis using CT scans can result in more successful treatment. CT is one of the most versatile and powerful diagnostic imaging modalities available today.
