Getting an MRI typically starts with a doctor’s order, but there are now ways to book one on your own. The path you take depends on whether you have insurance, what body part needs imaging, and how quickly you need results. Here’s how the process works from start to finish.
The Standard Route: Getting a Doctor’s Order
Most MRI scans begin with a visit to your primary care doctor or a specialist. You describe your symptoms, they examine you, and if imaging could change your diagnosis or treatment plan, they order the scan. Your doctor’s office then either schedules it for you or gives you a referral to an imaging center of your choice.
This is the route you’ll need if you want insurance to cover the cost. It’s also the route that gets you a physician who can interpret the results in context and recommend next steps. For most people, this is the simplest and most affordable option.
What Insurance Companies Require
If you have insurance, your MRI will likely need prior authorization before it’s approved. This means your doctor’s office submits paperwork proving the scan is medically necessary, and the insurance company reviews it before giving the green light. The process can take anywhere from a few days to a couple of weeks.
What counts as “medically necessary” varies by body part. For joint and spine MRIs, most insurers want to see that you’ve already tried conservative treatment like physical therapy for at least four to six weeks. A physical therapy discharge summary showing what was treated, when, and that a good-faith effort was made often helps secure approval. If you have a neurological deficit (like numbness or weakness), that requirement can be bypassed.
Brain MRIs have their own criteria. Headaches alone don’t usually justify one. Your doctor needs to document something more specific: increasing frequency or intensity, neurological abnormalities on exam, or other red flags. For dizziness, the documentation should show concern for a problem originating in the brain rather than the inner ear. For memory issues, insurers typically want to see results from cognitive testing and bloodwork ruling out reversible causes like thyroid problems or vitamin B12 deficiency.
For breast cancer screening MRIs, your age and estimated lifetime risk percentage are the key details. Follow-up scans after an abnormal mammogram need prior imaging reports and biopsy results included in the request.
If your authorization is denied, your doctor can appeal. Having thorough documentation from the start, including exam findings, failed treatments, and relevant test results, makes approval significantly easier.
Getting an MRI Without a Doctor’s Order
A growing number of private imaging clinics now let you schedule an MRI directly, no doctor’s referral required. Companies like First Look MRI operate in several states and allow you to book online, walk in, and receive your results the same day. The report gets emailed to you and faxed to a doctor of your choosing.
These clinics don’t accept insurance, so you pay out of pocket. The trade-off is speed and convenience: no waiting for authorization, no back-and-forth with an insurer. If something abnormal shows up, you take the results to your doctor or an urgent care center. This option works well if you want answers fast or if you’ve been struggling to get approval through traditional channels. Just keep in mind that without a physician guiding the process, you’re responsible for deciding what to do with the findings.
How Much an MRI Costs
MRI prices in the United States range widely, from $400 to $3,500, depending on the body part, whether contrast dye is used, and where you go. A brain MRI averages $1,600 to $3,000. Knee or shoulder scans run $600 to $2,000. Abdominal MRIs fall between $1,200 and $3,000. Adding contrast dye tacks on another $100 to $500.
The single biggest factor in price is the facility. Hospitals frequently charge four to ten times more for the same scan compared to a freestanding imaging center or orthopedic practice. If your doctor gives you a referral without specifying a location, it’s worth calling around. Many outpatient imaging centers post their prices or will quote you over the phone.
If you’re paying out of pocket, self-pay rates at independent imaging centers often fall between $250 and $600 for a standard MRI. These transparent pricing options can actually be cheaper than going through insurance if you have a high deductible.
Open vs. Closed MRI Machines
Traditional closed MRI machines are narrow cylindrical tubes. You lie on a motorized table that slides into the center of a powerful magnet. These systems produce the sharpest, most detailed images and are preferred for complex cases like neurological imaging or evaluating very small structures. The downside is obvious: the tight space can trigger claustrophobia or anxiety, and larger patients may not fit comfortably.
Open MRI machines replace the tunnel with a wide table and open space on most sides, giving you a 270-degree unobstructed view during the scan. They run quieter, too. Open systems used to produce noticeably lower-quality images, but modern high-field open MRIs have closed that gap and now deliver diagnostic quality sufficient for the vast majority of clinical needs. If you’re claustrophobic, a larger person, elderly, have limited mobility, or experience chronic pain that makes lying still in a tube difficult, ask specifically about open MRI availability when scheduling.
Some facilities also have wide-bore closed MRIs, which split the difference: a wider tunnel opening than traditional machines but still technically enclosed. When you call to schedule, mention any concerns about claustrophobia or body size so the facility can match you to the right machine.
What to Expect During the Scan
Joint scans (knee, ankle, hip, elbow, wrist) are the quickest, typically lasting 25 to 45 minutes. Brain and spine exams average about 45 minutes. Abdominal and other body scans can take 45 to 60 minutes. If your scan requires contrast dye, add another 15 minutes or so.
You’ll lie on a padded table and need to stay as still as possible. The machine makes loud knocking and buzzing sounds, so you’ll be given earplugs or headphones. Most facilities let you listen to music. You can communicate with the technologist through an intercom at any point, and you’ll have a squeeze ball or button to signal if you need to stop.
Before the scan, you’ll remove anything metal: jewelry, belts, hair clips, and sometimes clothing with zippers or underwire. You’ll be asked about any metal implants, pacemakers, or shrapnel in your body, since the MRI’s powerful magnet can interact dangerously with certain metals. If you have older implants, bring documentation of the make and model so the facility can verify they’re MRI-safe.
When Contrast Dye Is Used
Some MRIs use a contrast agent injected into a vein through an IV to make certain tissues, blood vessels, or abnormalities show up more clearly. The most common type is gadolinium-based. Your doctor decides whether contrast is needed based on what they’re looking for; it’s common for brain tumor evaluations, infection, inflammation, and certain vascular studies.
Before receiving contrast, the facility will screen your kidney function, usually with a recent blood test. People with significantly reduced kidney function face a rare but serious risk of a condition that causes skin and tissue thickening. The FDA has also noted that small amounts of gadolinium can remain in the body after injection, though no harmful effects from brain retention have been identified to date. If you’re pregnant, have kidney disease, or have had allergic reactions to contrast agents before, make sure the imaging center knows ahead of time.
How to Get Results Faster
At most facilities, a radiologist reads your images and sends a report to your ordering physician within one to three business days. Your doctor then contacts you to discuss the findings. If you want faster turnaround, ask about it when scheduling. Some outpatient centers offer same-day or next-day reads. Direct-access clinics that don’t require a doctor’s order often email results the same day.
Under federal rules, imaging results must also be made available to you through your patient portal, sometimes before your doctor has had a chance to review them. Seeing medical terminology in a raw radiology report can be alarming if you don’t know what’s routine. Phrases like “mild degenerative changes” are extremely common and often clinically insignificant, so try not to panic before speaking with your doctor about what the findings actually mean for you.
