Computerized Tomography (CT) Scan

CT, or computerized tomography, combines radiation and computer technology to produce images that provide a cross-section image of the body ("slices") and reconstruct body parts into 3D images.

Depending on the type of CT scan you are having, you will have different preparations.

If you are having your CT scan with contrast (dye), the technologist will give you contrast to drink or will place an IV in a vein in your arm. When the contrast first is absorbed into your system, you may feel flushed and have a copper taste in your mouth, but these will pass in a few seconds.

You will then be asked to lie on a table in front of the scanner and hold very still. The table will move very slowly into and out of the scanner, which is shaped like a doughnut.

Once your procedure is complete, the technologist will remove the IV, if needed, and your results should be available to your doctor within 24 hours.
