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.
If the MRI test is ordered by a surgeon or a specialist, then there are many chances that the results for the MRI test would also be interpreted by those doctors or surgeons who ordered for the MRI test or for the MRI scan. How long does it take to get MRI results also depends on how soon are the results required.It is possible that the patient is in a critical condition and the doctor requires an urgent MRI.ow long does it take to get MRI results also depends on how soon are the results required.
