CT Scan

CT or CAT scanning (Computerized Axial Tomography) uses cross-sectional x-ray imaging to view the human anatomy. University Radiology Associates located in downtown Syracuse has a state of the art 16-slice system CT Scanner. Scanning times are much shorter (important for patients who cannot sit still or have difficulty breathing), and the thinner-sliced images enable very small anatomic regions to be visualized. In addition, recent acquisition of a 64 slice CT scanner as part of a PET/CT unit allows unequaled quality CT scanning with advanced dose reduction technologies which limits radiation exposure to patients having these CT studies.

The CT is an open circular unit in which you pass through while lying in different positions.

Most examinations take under 30 minutes to perform depending on the procedure being done. Some examinations, such as abdominal imaging studies, require that you drink contrast prior to the examination to help separate the organs in the abdomen. There are also examinations that require IV contrast to enhance the study.

A technologist will explain the procedure and answer any questions that you may have. The technologist will be with you during the examination.

CT colonography (also known as virtual colonoscopy) is a non-invasive examination approved by the American Cancer Society for colon cancer screening. Unlike colonoscopy, where an endoscope is inserted into the colon via the rectum and which requires sedation, the patient undergoes a low dose radiation CT (computerized tomography) scan of the abdomen and pelvis after the colon is insufflated with gas (CO2). A 3D model of the colon is then reconstructed on a computer workstation from the cross-sectional CT images of the abdomen and pelvis. Using the workstation, a radiologist is then able to "fly" through and see the inside of the colon to look for pre cancerous polyps. This examination is indicated for patients that are of average risk for colon cancer and is the examination of choice after a failed colonoscopy
