Computed Tomography Can Clear the Contrast Images of the Body Organs
Computed tomography refers to the specialized X-ray imaging technique that employs computed processing for the generation of images. It can be performed plain or after the infusion of the computed tomography contrast agent. The application of digital geometry processing can generate three-dimensional images of the body organs. These images are called sections or cuts because they appear to resemble cross-sections of the body. The CT technique can eliminate the problem arising of the conventional X-rays.
CT scan is also called Computed Axial Tomography (CAT). It is used for the non-invasive imaging procedure to diagnose and treatment of several diseases. The images are combined with the aid of computer generating, unique, three-dimensional (3D) images of the body’s internal part. The computed tomography contrast imaging technology combines a long series if X-ray imaging of many sections to the targeted part of the body.
There are minimal disadvantages of CT scanning, and much less than any other imaging procedure. The excessive radiation may carry small risk of cancer. However, this type of risk is minimal with CAT scanning and overlapped with its benefits. It is not recommended for pregnant mother due to risk of the fetus. Female patients should inform their physician if there is any possibility of their pregnancy.
Computed tomography is being applied for the preventive medicine or screening procedures such as CT colonography for patients with a high risk of colon cancer, or full-motion heart scans for patients with high risk of heart disease. Computed tomography generates contrast images through the full-body scans. In many cases, this technology comes as a controversial practice, given its lack of proven benefit, cost, radiation exposure, and the risk of finding 'incidental' abnormalities.
