[|AI|]  Hi, You have sensory disturbance distributed over certain areas of the body. The doctors are most likely trying to look for neurological evidences on the scan. You most likely had a plain MRI scan. The second scan would be a contrast scan. During the second scan (contrast) - non-ionic gadolinium contrast scan, you will receive an injection of gadolinium contrast material before taking you into the scan room. This contrast scan will highlight suspicious areas which will help the doctors diagnose and treat you efficiently. I hope the process is clear to you now. Good luck!!
