CT Scan
Computed tomography (CT) creates detailed images of your body's internal organs using X-rays with computer technology. The doughnut-shaped scanner uses radiation to create cross-sectional images, or "slices," that help physicians detect tumors, heart disease or internal injuries or bleeding.
A CT scan may require that you not eat or drink if you have to drink a contrast liquid or have a contrast dye injected before the test. The contrast dye is used to help healthcare providers see body structures more clearly.
The exam usually lasts less than an hour, including any preparations, though the actual scan may only last a minute or two.
