CT is used in cancer in many different ways: To detect abnormal growths. To help diagnose the presence of a tumor. To provide information about the stage of a cancer. To determine exactly where to perform (i.e., guide) a biopsy procedure.
Positron emission tomography (PET) scanning combined with CTA is on the horizon for the detection of heart disease. PET scans are a form of nuclear medicine -- nuclear being the small dose of radioactive material you are injected with before the test (the radiation exposure is similar to that of a standard X-ray). As with CTA, PET involves a doughnut-like scanning device that takes the images.
