CT with IV Contrast and Oral Contrast

Computed Tomography (CT) is a test that combines x-rays and computer scans. The result is a detailed picture that can show problems with soft tissues, organs (such as your kidneys or lungs) and bones.

  • You will be given contrast through an intravenous (IV) line.
  • You may feel warm or flushed during the injection of the IV contrast.
