Have An Mri After Having A Hip Replacement

Magnetic resonance imaging (MRI) is a test that helps physicians diagnose and treat a range of conditions. You can have a MRI after receiving a hip replacement as long as the MRI is not focusing on the area near the hip implant. The materials used for hip replacements are made of metals that will distort the image of the MRI.


Hip Replacement Surgery


Hip replacement surgery involves the removal of damaged cartilage and bone, reconditioning the pelvis socket and replacement of the ball or femur. Hip replacement materials consist of chrome cobalt, polyethylene plastic, titanium alloy and possibly ceramics, all of which can affect the image of an MRI.


MRI Scans


MRI scans use strong magnets and radio waves to take noninvasive pictures of your body. One MRI scan can produce an abundance of images that can be stored on a computer or printed on film.


Risk


Patients who have heart pacemakers, metal implants or metal chips in the eye region cannot be scanned with an MRI because the magnet that is used in the MRI procedure may move the metal that is located within these areas of the body.


Fact


According to the National Institutes of Health, an MRI may help to uncover reasons for failed hip replacement procedures.








Tip








Before having any type of scan or exam that involves radiation or magnetic scans you should always reveal any prior surgeries or existing medical conditions first.
