Computer Tomography (CT)
Computed tomography (CT) is another sophisticated imaging technique that can show anatomy at different levels within the body. During CT imaging, the xray source rotates around the patient, and each rotation produces a single cross-sectional "slice", like the slices in a loaf of bread. CT allows physicians to see a horizontal piece of the body, just as if you were taking a slice of bread out of a loaf. CT scans are used to diagnose many conditions. They may be used to examine the head to check for bleeding, tumors, blood clots or signs of stroke. In other parts of the body, CT may be used to tell whether a growth is solid or fluid-filled, determine an organ's size and shape and evaluate many different diseases.
