What Is Computed Tomography (CT)?

Computed tomography (CT) is a diagnostic imaging tool that allows radiologists to view patient anatomy non-invasively. A CT scanner uses X-rays and a series of detectors that rotate continuously around a patient. The X-rays pass through a patient’s body and get absorbed by detectors. The collected data is analyzed by a computer and creates several cross-sectional images of the patient.  

CT is used to image many parts of the body, including the brain, face, neck, spine, chest, abdomen, and extremities. CT scanning is useful in diagnosing a wide range of medical complications, including trauma, abdominal pain, GI complications, evaluation of infections, cancer, evaluation of main vessels, and blood clots.

Industry-Leading Equipment

In order to provide the highest level of care for our patients, University of Utah Health has invested in the latest industry-leading Siemens CT imaging equipment, including one Dual Source 128 slice and two single source 128 scanners. These offer excellent cardiac imaging 3D reconstruction and are equipped with Siemens CARE Dose4D, which automatically adjusts radiation dose according to patient size. University CT services are also accredited by the ACR and all CT technologists are certified through the ARRT.
