Originally developed to image the brain, CT scans are now used to visualize tissues and organs throughout the body, detecting tumors, infections, injuries, and bone or spinal issues. CT angiography (CTA) provides detailed views of blood vessels and often replaces more invasive procedures.

Depending on the exam, you may receive contrast dye to enhance image clarity, either by drinking it or through an IV. CT uses a low-dose X-ray beam, offering clear, detailed images with minimal radiation exposure.

During the scan, you’ll lie on a table that moves through a doughnut-shaped scanner as it captures cross-sectional images. Most exams take only a few minutes. Results are reviewed by a radiologist and shared electronically with your doctor.

Notify your doctor or technologist if you are or may be pregnant.
