cns magnetic resonance imaging
"I had a bad reaction to this dye!  I have had 5 previous MRI s with no problems at all to previously used dyes. It burned and made my arm ache on injection and 6 min later when done and I tried to get up I passed out and my blood pressure dropped.  They watched me for almost an hour after and I stabilized.  After going home my heartbeat was irregular and I was very tired.  I am a 56 yr old female with high blood pressure controlled by Micardis 40 mg."
