LOOKING FOR
ARTERIAL PLAQUE
A CT angiogram is a valuable test for detecting plaque buildup in your arteries. It requires injecting a contrast dye into your vein, which helps the CT scanner visualize blood flow throughout your body.
A CT angiogram is less invasive than a catheter angiography, which requires placing a catheter through a small incision in your skin to inject the contrast dye.
About your visit
WHAT TO EXPECT
Please arrive 30 minutes prior to your scheduled appointment time. This will give you time to fill out any necessary forms and change into scrubs if needed.
For the scan, you will lie down on a CT table. The table moves through the CT scanner while obtaining images. Depending on your healthcare provider’s request, you may receive a “contrast” liquid by mouth and/or IV. This contrast helps provide greater visibility in your images. Once started, the procedure can take from five to 15 minutes.
CT scans combine a series of X-ray views taken from many different angles, which a computer then uses to create 3D, cross-sectional images of the bones and soft tissues needing examination. Although CT does use radiation to produce these images, we utilize “low-dose” technology, which decreases your radiation exposure compared to standard X-ray technology.
