Computed tomography, or CT/CAT scan, is a routinely performed imaging diagnostic technique that uses three - dimensional image reconstruction to integrate X-ray pictures from many angles into a single image.
Any portion or structure of the body, including the bones, soft tissues, and blood arteries, can have cross-sectional images, or'slices' obtained. Unlike an X-ray, which only produces one image, a CT scan produces numerous images, which improves diagnostic accuracy and clarity.
Internal injuries, trauma, tumours, fractures, and other illnesses can all benefit from a CT scan. This imaging test is also used to guide surgeries, radiation therapy, and biopsy procedures, as well as to assess the efficacy of ongoing treatments.
A CT scan is a painless and non-invasive method that does not require the use of contrast dye. For specific medical situations, however, a Contrast-CT scan is performed, in which the contrast material is given orally or intravenously (IV). When examining soft tissue, the contrast material is extremely effective since it blocks X-rays, making the target area appear white on the scan. It has few to no negative effects and is excreted in the urine within 24 hours.
