What Happens During the Test?
Depending on the type of scan you need, a dye may be injected into your vein so the radiologist can better see the body structures on the image.
After the dye is injected, you may feel flushed or you may have a metallic taste in your mouth. These are common reactions. If you notice shortness of breath or any unusual symptoms, tell the technician.
The technician will help you lie in the correct position on the examining table. The table will then automatically move into place for imaging. Lie as still as possible during the entire procedure. Movement could blur the images. You may be asked to hold your breath briefly while each X-ray image is taken.
What Happens After the Test?
Generally, you can resume your usual activities and normal meals right away. Your doctor will discuss the results with you.
