Hello everyone..I just found this site and need an answer to my burning question. I had an mri yesterday because my symptoms are: loss of memory, hand numbness, tingling, ringing in ears....mostly because of the memory loss. Anyway, doc ordered a contrast agent and the tech. told me she'd do 20 min of imaging and then do the contrast drug. I came out and she say radiologist said a contrast agent was not needed. couldn't tell me why of course. To me, that means he saw the problem without needed contrast...right? if he didn't see anything, to me, is when he would then use the drug. PLEASE someone give me their honest opinion. thanks
