Guide To Ct Scan
More Computed tomography, also called CT or CT scan, is a process that uses X-rays and computer technology to make cross-sectional images of the body. A series of X-ray pictures, each a thin slice, are put together in a computer to form a three-dimensional view of the inside of your body. If an X-ray is like looking at a photo of a heart, a CT scan is like looking at a model that you can pick up and examine from any angle. In a CT scan, X-rays pass through the body and are analyzed by a computer. The computer builds an image based on the amount of X-rays passing through tissues of different thickness.
For example, bone appears white on a CT scan, and gas bubbles in the stomach and intestines appear black. You can have a CT scan in an outpatient facility or in a hospital. The procedure is painless and takes about 20 minutes, but can be longer or shorter depending on the area of the body being scanned. What It's Used For CT can reveal abnormal masses that may be cancerous tumors. CT scans show the size and shape of the tumor, its precise location in the body, and whether the tumor is solid or hollow. Sometimes, a CT scan can tell the difference between a noncancerous and cancerous tumor, although a biopsy or other test is needed to make the final diagnosis. In a biopsy, a small piece of tissue is removed to be examined in a laboratory.
During a CT-guided biopsy, the physician will use the CT scan as a guide as he or she inserts the needle into the right location to remove a sample of the tumor. In addition to detecting cancer, CT scans have many other uses. They can show abscesses and other infections, strokes, head injuries and bleeding inside the skull, as well as a variety of other medical conditions. For obese patients, CT scanning may be a more useful diagnostic tool than ultrasound, because large amounts of body fat can interfere with ultrasound waves, producing poor images. Preparation CT scanning usually does not require any special preparation. Remove jewelry in the area being scanned.
