Functional magnetic resonance imaging (fMRI) is a relatively new procedure that uses MR imaging to measure the tiny metabolic changes that take place in an active part of the brain.
A magnetic resonance imaging (MRI) scan is a painless procedure that lasts 15 to 90 minutes, depending on the size of the area being scanned and the number of images being taken.epending on the size of the area being scanned and how many images are taken, the whole procedure will take 15 to 90 minutes. The MRI scanner will make loud tapping noises at certain times during the procedure.
A: Most MRI's are read within 24 hours and the results sent to your doctor. He should have seen the results probably 48 hours after your scan. You are getting the run around, either that or they can't find the printed MRI report that was sent to your doctor and that is why you are getting the run around.
