A computerized tomography urogram uses X-rays which produce images of the body parts in slices and sends the images to a computer to reconstruct the two-dimensional images. During the procedure, the patient is placed in a supine position, and an intravenous line is inserted into a hand vein to deliver the dye. Then the table slowly moves through the scanner to capture images of the urinary system. Finally, the intravenous line is removed, and a dressing is placed.
