How Can I Prepare for a CT Scan & What Should I Expect?

Depending on the imaging tests you require, you’ll need to prepare in a specific way your doctor will discuss with you in advance. Most patients are required to fast for at least four hours before their scan and can expect to be in the AVH Radiology Department for 90 minutes up to 3 hours. The process of taking the scan itself takes much less time. You may be asked to drink an oral contrast agent approximately 90 minutes before your scan. If your physician orders intravenous (IV) contrast, you may, for a short time, feel a slight warm sensation in your body, which is normal.

The CT machine looks like a large square doughnut and only covers the area that is being examined. Before entering the scanning room, you may be asked to remove anything metallic. Once you’re positioned on the table, the scan will begin. During the exam, you will be in the room alone; however, your technologist will see and hear you throughout the whole procedure.

Our Technology: G.E. VCT 64-Slice CT Scanners

Our Radiology Department has 2 advanced 64 multi-slice CT scanners. Volume coverage speeds up the scan process, making it a highly effective imaging option for emergency, trauma, and acute care situations. Higher speed scanning equates to clearer, sharper images with fewer potential problems like patient movement or a beating heart's motion. The scanner also performs CT angiography for physicians evaluating their patients’ arteries to assess their function, observe anatomy, and detect the degree of coronary heart disease. Patients are exposed to minimal radiation, thanks to automated dose‑reduction. Both CT scanners are accredited by American College of Radiology (ACR).

Check with your physician’s office for the appropriate preparation for your test, or call the Radiology Department at 661‑949‑5705.
