CT (computed tomography), also called a CAT or CT scan, uses special x-ray equipment to obtain image data of the body and utilizing computer processing of that information shows a cross-section of the body’s tissues and organs. This is almost like looking at slices of bread taken from a loaf.
CT imaging is very useful because it can show several types of tissue. It not only images bone and air like conventional radiographs, but also clearly demonstrates soft tissue structures of the body: organs, muscles and blood vessels. Some of these structures would only appear as indistinct gray masses on conventional radiographs. Moreover, CT imaging can distinguish between normal and diseased or injured tissue based on changes in size, shape and appearance of the tissue. These scans are used to look at all parts of the body. A wide variety of problems and diseases are evaluated such as injuries (trauma), cardiovascular disease, infectious disease, inflammation and cancer. CT scanners are one of the most versatile diagnostic imaging tools available today.
Austin Radiological Association has MDCT (multi-detector CT) scanners at all of its facilities. With MDCT, the refinements in detector technology support faster, higher quality image acquisition with less radiation exposure. These “spiral” or “helical” scanners can obtain images of the body within a single breath hold. MDCT also allows applications such as CT angiography to be more successful.
