There are three bones in the arm.

• The humerus is the bone in the upper arm.
• The ulna and radius are located in the lower arm. They join the humerus at the elbow joint.

A CT scan of the arm (upper extremity) is a test that uses X-rays to create detailed images of the bones, tissues and structures in your arm.

Here are some things you should know before having a CT scan:

• Your healthcare provider may tell you not to eat or drink for at least four hours before the test.
• The test is painless, but you must lie still during the exam. Moving can blur the images.
• Generally, a complete scan takes only a few minutes. New scanners work even faster.

The costs for this test include the charge for the test (facility charge) and physician charges (for performing or interpreting the test). You may get separate bills from the facility and the physician's office.

What should I ask my health care provider before having this test?

• Can I eat before the test? If not, how many hours before the test should I stop eating?
• Is there any special preparation for the test? (If so, get clear steps to follow.)
• What is the reason for the test? Are the test results likely to change my treatment plan? If not, why do I need the test?
• Are there any less expensive, but effective, alternatives to my getting this test?
