Indications for use of CT  
 

CT is widely used to help diagnose a variety of different problems and symptoms. It is excellent for evaluating lung parenchyma, as well as soft tissues of the neck, chest, abdomen and pelvis. It is also a quick and relatively inexpensive way to evaluate the brain.

CT can be used as a primary imaging tool to evaluate a patient's symptoms, or can provide additional information when other tests are inconclusive. CT is currently widely available and easily accessible.

It is beyond the intentions of this submodule to discuss all of the potential uses of CT, but this should serve as a broad guideline to help one understand the general uses of CT.
