There are three major bones in the leg.

• The femur (thighbone) is the bone in the upper leg.
• The tibia (shinbone) and fibula (the smaller calf bone) are located in the lower leg. They join the femur at the knee joint.

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

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?
