Computed Tomography (CT Scan, CAT Scan)
Computed Tomography is better known as CT scan or CAT scan. CT scanning uses highly sophisticated imaging equipment to obtain images that are essentially slices through the body. This is a highly effective way of “seeing inside the body”. CT scanners initially obtained images a slice at a time, and the process was fairly time consuming. Newer CT scanners, called multi-slice or multi-detector scanners, can acquire multiple slices at one time and can even acquire volume images. This allows us to look at pictures of the body in a variety of two-dimensional planes and even as three-dimensional images.

Clinical Radiologists, S.C. (CRSC), has been at the forefront of CT scanning since its inception. At Memorial Medical Center in Springfield, CRSC used the second brain CT scanner operating in the United States. We also had one of the first body CT scanners in the country. We have continued to lead the way, introducing multislice scanning, three-dimensional imaging, and a variety of new applications, such as CT angiography and CT of the heart, to Central Illinois. We have also been leaders in electronic transmission of CT images, so that our radiologists in Springfield can view CT scans from any of our sites, any time, night or day.

All radiologists receive extensive training in interpretations of CT scans during their residencies. CRSC has several radiologists with advanced fellowship training in CT of the nervous system; CT of the chest, abdomen and pelvis; CT of the heart and blood vessels; CT of the musculoskeletal system; and pediatric CT.

What preparation is needed?
Some CT scans do not require any special preparation. For other examinations, you will be asked to fast prior to the CT scan. For some abdominal or pelvic CT scans you will be asked to drink water or an oral contrast agent. The oral contrast agent will allow us to evaluate the bowel and some other abdominal structures. Please visit our section on exam preparation for additional information.

What happens during the examination?
You will be positioned comfortably on the scanner table, usually on your back. The picture-taking portion of the scanner looks like a giant donut. The table will slide through the “donut” as images are obtained. For most CT scans you will be asked to hold your breath during the exam. You will need to hold as still as possible, since movement can result in poor quality images.

Many examinations will be performed with the injection of a contrast agent (x-ray dye) through an IV. The dye may cause a warm sensation throughout your body and a metallic taste. The contrast is safe, but reactions do rarely occur. If you have any discomfort other than a warm sensation and metallic taste, let the CT technologist know. The technologist will monitor the first part of the dye injection and will observe the entire exam from the adjacent control room. The contrast agent may not be safe for some patients with kidney disease; you will be given a questionnaire prior to receiving any x-ray dye. If necessary, you may be asked to have a blood test to check kidney function prior to receiving the dye. People taking some oral medicines for diabetes will be asked to withhold those medicines for 48 hours after receiving the contrast. If you have any questions or concerns regarding the contrast agent, the technologist or radiologist can address any concerns.
