When is a CT scan required?

CT scans can be used for various imaging and diagnostic needs. This kind of imaging technique can be useful for finding tumors, unusual masses, diagnosing infections and bone fractures. A CT scan is also useful for understanding internal structures and can identify internal bleeding or injury.
