What happens during an MRI scan?

ANSWER

As it begins, you'll hear the equipment making a muffled thumping sound that will last for several minutes. Other than the sound, you shouldn’t feel anything unusual during the scanning.

For some MRI exams, you'll need a shot of a "contrast material" into your vein. It helps doctors see certain structures in your brain on the scan images.

You also may get a drug to make you feel relaxed and drowsy.
