CT Head - Contrast
What is CT Head - Contrast?
CT Head-Contrast is a diagnostic imaging test that combines a Computed Tomography scan with a special dye injected into the blood vessels. This dye helps light up the parts of the brain that need to be examined. During a CT Head-Contrast, the X-ray beam moves in a circle around the head, allowing many different views of the brain. It produces images of the brain and helps detect brain cancer, some primary brain tumors, and brain abscesses.
The dye used in the contrast material can cause allergic reactions or kidney damage in some patients. Repeated exposure to these scans can increase your risk of cancer. A radiologist will interpret the results, and you may have to consult your doctor for further treatment.
