How long does it take for a brain mri?

20-60 minutes: It varies depending on how many sequences are required. A basic scan runs about 20 minutes, but if the scan requires specialized looks at specific areas (such as the pituitary, the temporal lobes, or the orbits), or if additional sequences with contrast agent are needed, it can take significantly longer.

40 min to 2 hrs: The length can vary but on average a brain MRI will run 40 min to 2 hours depending on the sequence used, whether there is a contrast used, and other factors.
