A CT scan uses radiation (x-rays) to produce images whereas an MRI uses magnetism and radiofrequency waves (no radiation). A CT scan is fast, usually lasting 2 to 5 minutes. An MRI can take much longer (15 or more minutes) depending on the body part being scanned. Anyone can get a CT scan. There are some conditions that prohibit the use of an MRI scan due to the strong magnetic fields required for the test, the most common being presence of a pacemaker, metallic foreign bodies (especially in sensitive areas like the eyes or near vital organs or vessels), and brain aneurysm clips.

In the case of an exam for the lungs, a CT scan is the best type of scan for the resolution needed for evaluating the lungs. An MRI is usually not used for evaluating the lungs.
