How long do MRI results take? (And what to do while you wait)
Most routine MRI results are available within 1–3 business days. Urgent or STAT MRIs can be read within hours or even minutes. The radiology report is written by a radiologist, not automatically generated — this takes time. You can usually access your report through a patient portal. If you have your DICOM images, you can also upload them to understand the findings while you wait for your doctor's appointment.
Waiting for MRI results is one of the most anxiety-provoking parts of medical care. This guide explains how long you should expect to wait, what affects that timeline, and what you can do to understand your results sooner.
Typical MRI result timelines
Why results take as long as they do
MRI interpretation is not automated. A human radiologist must:
- Review hundreds of images — a single brain MRI may generate 500–1,000 images across multiple sequences (T1, T2, FLAIR, DWI, post-contrast, etc.)
- Compare with prior imaging — if you've had prior MRIs, the radiologist reviews those as well to assess change over time
- Dictate a detailed report — the radiologist speaks the report aloud; it is transcribed, then reviewed and signed
- Work through a full worklist — radiology departments read many studies per day in order of urgency
Weekend scans, holiday periods, and high-volume days can delay turnaround. Studies requiring subspecialist review (neuroradiology, musculoskeletal radiology, breast imaging) may add additional time.
How to get your results
Patient portal (MyChart, FollowMyHealth, etc.)
Most hospitals and large imaging centers now use patient portals that automatically release radiology reports when they are signed. Some systems release immediately; others hold for 24–72 hours to allow your referring doctor to review first. If you don't have portal access, ask your imaging facility or doctor's office to set it up.
Your ordering doctor
Your referring physician (the doctor who ordered the MRI) is notified when results are available. They will either call you or message you through the portal, or discuss results at a follow-up appointment. If you haven't heard within 3–5 business days, it's reasonable to call and ask.
Requesting your report and images directly
You have a legal right to your medical records, including your radiology report and your DICOM image files. You can request these directly from the imaging center's medical records department. DICOM images are typically provided on a disc or via a download link.
What the radiology report contains
When you receive your report, it will typically have these sections:
- Clinical indication — why the MRI was ordered (e.g., "evaluate for disc herniation," "headache workup")
- Technique — what sequences were performed, whether contrast was used, field strength (1.5T, 3T)
- Comparison — whether prior imaging was available for comparison
- Findings — detailed description of each structure examined
- Impression — the radiologist's summary and key conclusions, often numbered by priority
- Recommendations — follow-up imaging, correlation with clinical findings, referral suggestions
What to do while you're waiting
If you have access to your DICOM images already
Many imaging centers provide same-day access to your DICOM files (the actual scan images), even before the report is signed. If you've already received your images on a disc or download link, you can upload them to get a plain-English explanation of the findings — including which frames show specific findings and what the terminology means.
Write down your questions
While waiting, note any symptoms you want to discuss and questions you want answered when you speak with your doctor:
- What did the MRI show?
- Is this finding new compared to prior imaging?
- What does this mean for my diagnosis?
- What is the next step — additional imaging, specialist referral, or treatment?
- Is there anything urgent I should watch for while I wait for my appointment?
When to call your doctor before your appointment
If your symptoms worsen significantly while waiting, or if you develop new symptoms, call your doctor's office. Don't wait for a scheduled appointment if something changes.

Frequently asked questions
How long does it take to get MRI results?
Most routine outpatient MRI results are available within 1–3 business days. Urgent MRIs can be read within hours. Emergency stroke protocol MRIs are read in minutes. The timeline depends on urgency, facility volume, and whether subspecialist review is needed.
Why do MRI results take so long?
A radiologist must manually review hundreds of images, compare with prior scans, dictate a detailed report, and have it transcribed and signed. A brain MRI may produce 500–1,000 images across multiple sequences. This is not automated — it requires careful human interpretation.
Can I see my MRI results online?
Yes — most hospitals and imaging centers now offer patient portal access where reports are released when signed by the radiologist. Some portals release immediately; others hold 24–72 hours to allow your doctor to review first. You can also request your DICOM images separately from the radiology department.
What is the difference between the radiology report and my DICOM images?
The radiology report is the written interpretation — it describes findings, provides conclusions, and gives recommendations. DICOM images are the actual scan data — hundreds of cross-sectional images from the MRI. The report tells you what the radiologist found; the DICOM images let you see exactly what the radiologist reviewed.
