Before your examIn some cases, your doctor may request that a dye is used to provide contrast in the scan. This is most frequently administered through an IV or by mouth. For exams that require contrast, an additional blood test is typically required to evaluate your kidney function prior to your CT scan. In most cases, fasting before your exam is not necessary however special instructions may be provided by your doctor if you are a diabetic or have allergies. Wear comfortable clothing around the area to be scanned. You may also be asked to wear a gown. Learn more about CT scanning technology from the www.radiologyinfo.org. |
