Thanks Joie! I didn't say anything to the tech because I was trying hard to stay still so I wouldn't have to stay in longer! :-)
Arms are still sore and a bit weak today but none the worse for wear. Glad to know that sort of thing does happen. With my hyperreflexia in arms and legs I never know what will happen. Next MRI I will be more prepared.

Sorry to hear you had so many adventures getting to your scans, but happy to hear you had them! It's not unusual to have spasms, twitching, etc in mri machine. The magnetic field impacts the electrical impulses in the muscles causing them to fire. I had the same experience and researched it extensively afterwards.
