What affects how long an MRI takes?
The time is affected by which area is to be examined. MRI of the knee, MRI of the brain, MRI of the lumbar spine, MRI of the abdomen and MRI of the whole body have different scopes.
More image series take longer. If contrast media is needed, extra steps are often added before or during the examination.
It is also common for some time to be spent on safety issues, changing and positioning before the image capture begins.
- Body part
- Number of image series
- Contrast agent
- preparations
- Movement and retake
Why do some MRI scans take longer?
MRI is based on multiple image series that show tissues in different ways. This is part of the strength of the method, but it also means that the examination can take time.
If the question is broad, such as in a full-body MRI, several areas need to be included. If the question is narrow, the examination can often focus on a smaller area.
The survey period should therefore be understood based on what you want to get answers to.
What happens during the MRI scan?
During the imaging, you lie still on a couch. The camera takes images in sequences and you will often hear knocking or thumping sounds.
The staff can communicate with you during the examination. You will usually be given hearing protection and instructions on how to lie down.
If you move a lot, the image quality can be affected, which sometimes means that a series of images needs to be retaken.
- Lie still
- Follow instructions
- Wear hearing protection
- Tell me if you feel uncomfortable.
- Count on multiple image series
When should time not guide the decision?
In the event of acute symptoms, it is more important to seek care immediately than to look for a quick private MRI appointment. The healthcare provider will then decide which examination is needed first.
Sudden neurological symptoms, chest pain, severe abdominal pain, difficulty breathing or rapidly deteriorating general condition require urgent assessment.
Planned MRI is best suited for non-urgent issues where the right examination can be selected at a slower pace.
Planned private MRI should not replace emergency care for sudden, severe or rapidly worsening symptoms.
Investigation time and response time are different things
Examination time is the time in and around the MRI scanner. Response time is the time until the images are reviewed and the report is ready.
A quick image acquisition does not automatically mean a quick response. Radiological assessment and report are important parts of quality.
When comparing MRI options, you should therefore ask about examination time, response time, and what is included afterwards.
What happens after the pictures are taken?
After the imaging is done, the images are reviewed by a radiologist. The radiologist describes relevant findings in a written report.
The report then needs to be understood in relation to symptoms and questions. In some cases, further healthcare contact or additional examination is needed.
A quick answer is valuable, but it also needs to be clear and medically useful.
Limitations and next steps
How long does an MRI take? needs to be understood as part of a larger medical picture. Imaging can provide important answers, but it alone cannot explain all symptoms or replace a clinical assessment.
A finding on MRI may be significant, but may also be an age-related or benign change. Similarly, a normal MRI response may need to be followed up if symptoms persist or change.
The best next step therefore depends on what the examination shows, how your symptoms develop, and whether there are risk factors, previous illnesses, or other test results to consider.
- Normal variant or incidental finding
- Findings that need to be followed up
- Supplementary sampling
- Referral or specialist assessment
- New assessment in case of deterioration
