CT scan can be ordered for several parts of the body based on the issue faced by the patient. For example, a chest CT scan is conducted over the chest area, with the machine recording images strictly of the chest. Similarly, an abdominal CT or CAT scan is explicitly performed on the abdomen part of the body.

However, an abdominal CT scan is far superior in the visibility of the blood vessels, and soft tissues to the bones, almost like contrast material scanning. Multiple X-RAY images of the abdomen cavity give the doctor a different perspective to look at the problem and figure out the solution similarly.
