CT Scans

What Is A CT Scan?

Everything you need to know about getting a CT Scan in El Paso, TX

Computed Tomography commonly referred to as a CT Scan is a noninvasive medical test that combines special x-ray equipment with sophisticated computers to produce multiple images of the inside of your body. These cross-sectional images of the area being studied can then be examined on a computer monitor or printed. These images can be manipulated into different positions, allowing the radiologist to thoroughly examine any area of interest. Here at DOI, we have both a 16 slice and an 80 slice Toshiba Aquilion CT scanners, the latter being cardiac capable. These recently upgraded machines allow for reduced X-ray dose, higher resolution images, and more patient comfort as shorter breath holds are required.

The technologist begins by positioning you on the CT examination table, usually lying flat on your back or possibly on your side or on your stomach, depending on the area being studied. If contrast material is used it will be injected through an intravenous line (IV). Next, the table will move quickly through the scanner to determine the correct starting position for the scans. Finally, the table will move slowly through the machine as the actual CT scanning is being performed.

What Does A CT Scan Examine?

A CT scan can provide greater clarity and reveals additional details when compared to a regular x-ray exam. A CT scan can be used to study all parts of your body, such as the chest, abdomen, pelvis, or an arm or leg.
