Back jack..aka Vertiflex....

If that MRI machine is anything like the one they used on me last week, ya know those earplugs you use when you're taking photos of the nitro cars? They won't be enough! I'll never complain about a back-up alarm on a tractor ever again.

I had an MRI last week . They gave me sound deadening earphones with Music and they could talk to me through them also
