CT Scan: Purpose, Procedure, Risks, Side-Effects, Results CT scan stands for computed tomography. It is a method of displaying ultrasound images and x-ray images of the human body. A CT scan may be used to visualize head, shoulders, spine, heart, abdomen, knee, and chest. Computerized tomography is a combination of X-rays and a computer which creates images of your organs, bones, and tissues. It shows more detail than a regular or traditional method of X-ray scan. It is used to visualize a two-dimensional image. It typically helps to achieve a more detailed view of an injury or disorder, mostly at the time of an emergency.
Purpose A CT scan usually has many uses, but the best one is that it quickly examines people who may have any injuries that may be caused on internal parts in the form of accidents or other types of trauma (physical injury). The procedure is used to diagnose diseases and injuries for further treatment. The scan occurs in a narrow beam circling around your body. This provides a series of images from different angles of the internal body parts. The computer deals with these scans on top of the other to create a detailed image of your organs, bones, or blood vessels. Procedure A radiology technologist will execute the CT scan. During the test, you will have to lie on a table inside a large, doughnut-shaped CT machine. The table slowly moves through the scanner, the X-rays rotate around the body. You might hear a whirring or buzzing noise, you will be asked to stay very still as movement can blur the image and the extract will get disturbed. You may be asked to hold your breath at times as well. It may take from a few minutes to half an hour to complete the procedure. You might be asked to not eat or drink a few hours before the scan. You may be asked to wear a hospital gown and remove all metal objects, such as jewellery, ornaments,
