Contrast notes
Most musculoskeletal MRI is performed without contrast. Gadolinium is reserved for select indications — post-operative scar vs. recurrent disc, suspected infection or tumor, or arthrographic protocols. Your ordering physician and our radiologist will confirm contrast use before the exam, and kidney function is screened first when contrast is planned.
Prep summary
Most patients don't need special prep beyond completing the MRI/CT safety screening and removing metal jewelry. Specific prep (fasting, contrast, medication timing) is confirmed at scheduling.
Read the full MRI prep guideWhat to expect during the exam
Plan for 30–60 minutes at the imaging center. You'll change into a gown and remove all metal. A technologist positions you on the table with the coil over the area being imaged; the table then slides into the magnet.
MRI is loud — you'll wear ear protection and can listen to music or talk to the technologist through the intercom at any time. Holding still for each sequence (typically 2–5 minutes each) produces the sharpest images.
Results and report turnaround
Every study is interpreted by a board-certified radiologist — most by fellowship-trained sub-specialists in the relevant body system. Preliminary reads are typically available within a few hours, with the signed final report sent to your ordering provider the same business day.
You can also request a copy of the report and the imaging on disk for your own records or for a second opinion.

Frequently asked questions
How long does a lumbar MRI take?
30–45 minutes in the scanner; about an hour door-to-door.
Will I need contrast?
Most lumbar MRIs are non-contrast. Gadolinium is added for post-operative imaging to distinguish scar from recurrent disc, or for suspected tumor/infection.
Should I keep taking my pain medications before the exam?
Yes — taking your usual medications can help you lie comfortably still through the exam. Bring a list of medications to check-in.
Can I have a lumbar MRI if I'm claustrophobic?
Most patients tolerate our wide-bore scanners well. Several California locations also offer true-open MRI, and mild sedation can be arranged through your physician.
Will the MRI tell me why I have back pain?
Often yes — but back pain is multifactorial. The MRI shows structural causes (disc, nerve, stenosis); your physician correlates these with your exam and history.
How much does a lumbar MRI cost?
Insured patients pay only their plan's cost-share. We also offer transparent, discounted self-pay rates — call 800-558-2223 for a quote.
Do I need a referral?
Yes — insurers generally require a physician order and prior authorization. We handle the authorization process on your behalf.
