Hello @sunshinesally Researching the need for an MRI before arthroplasty implants brought up quite a few articles from different orthopedic practices (their websites) about the improvements in hip replacements with precision offered with the technology of the MRI. Also it allows the doctor to check for any tiny bone fractures not seen with an X-ray. The MRI can also pick up bruising on bones, checks for muscle, ligature and tendon interference, etc.

According to Radio Graphics (rsna.org)
“Magnetic resonance (MR) imaging has evolved into a powerful diagnostic tool for the evaluation of hip arthroplasty implants.”

Hopefully this helps allay your fears. I would think if his surgeon was at all concerned about anything amiss, he’d have discussed this with your husband at the consultation. But the doctor may want another tool to make sure your husband’s procedure goes smoothly. You could always call the surgeon’s office to ask about the MRI as well.

If your husband is at all uncomfortable with this scan…lying still or feeling claustrophobic, have his doctor offer an anti anxiety med such as lorazapam (Ativan). Has your husband ever had an MRI?
