Question
Hi Doctor Jackson:  I need to have an MRI done on my back, which will involve being in machine for at least 45 minutes, but I have severe claustrophobia.  For the first attempt I took a benzo (alprazolam) as instructed at the max dose and it didn't help at all.  They want  to reschedule the MRI with GENERAL anestheisa and that seems dangerous to me; they said that just IV sedation won't work because I would move too much.  I understand that general anes is safe in the OR with the anesthesiologist stanging right there, but is it safe for an MRI? Can the anesthesiologist even be standing next to that strong magnetic field for 45 min?  I can't get any answers here; they tell me to schedule the procedure and that I can ask my questions right before the MRI.  Thanks.

Answer
Hi Jerry
Bottom line is anaesthesia is just as safe in the MRI as it is in OR. There is no health problems in standing next to the MRI machine as long as you don't have any metal bits! Doesn't cause us any issues personally we just have to use special equipment that works within strong magnetic fields.
Personal advice - its a lot safer than someone trying to stun you long enough for the procedure.
Kind regards
