This cross-sectional imaging scan allows the radiologist to assess the spine for injury and other bony abnormalities using a rotating X-ray beam.
This exam may include injecting an iodine substance in the vein. Diabetic patients and those with allergies must inform the radiology staff and may need clearance from their doctor before the exam. Blood tests may also be required prior to the administration of contrast materials. Patients whose exam includes an injection may not eat or drink anything four hours before the test. During the injection, the patient may experience a warm sensation throughout the body and a metal taste in the mouth. This is normal.
During the exam, the patient lies on an exam table with arms positioned at the sides. Only a portion of the head is covered by the scanner as it takes pictures. The technologist is always able to see and hear the patient during the 15- to 30-minute exam.
