Congenital Heart Institute of Texas, San Antonio, Texas

Chest CT

Your child will be placed on a narrow table (gantry) that slides into the center of the scanner. If contrast media (dye) is to be administered, intravenous access will be placed in a small vein of a hand or arm. Much like standard photographic cameras, subject motion causes blurred images in CT. Therefore, your baby may be restrained to prevent motion during the scan. As the exam takes place, the gantry will advance small intervals through the scanner.
