Brain MRIs typically take anywhere from 30 minutes to over an hour to complete.
The exact duration of a brain MRI scan can vary depending on several factors:
- Specific Area Being Imaged: If the MRI focuses on a very specific and small area of the brain, it might be quicker than if the entire brain needs to be scanned.
- Number of Scans Required: The number of image sequences required will impact the overall time. A more detailed exam requiring multiple sequences naturally takes longer.
- Use of Contrast Dye: If a contrast dye is used, it can add a few minutes to the procedure. The dye helps to highlight certain structures or abnormalities in the brain.
- Type of MRI Machine: The specific MRI machine being used can also play a role. Newer, more advanced machines may be able to acquire images faster than older models.
- Patient Cooperation: Patient cooperation is crucial for obtaining clear images. Excessive movement can necessitate rescanning, thereby extending the overall scan time.
During the MRI, you will lie still inside a large, cylindrical machine. It's common to hear loud knocking or tapping noises. You'll likely be provided with earplugs or headphones to minimize the noise. If you're concerned about claustrophobia, speak with the doctor who ordered the MRI. They might prescribe a mild sedative to help you relax during the scan.
