Hi @libertyusa, I’ve had several MRIs from head to tailbone which take anywhere from 2.5 to 3 hours. I was also very claustrophobic and dreaded that first MRI! I couldn’t imagine surviving. ☺️ They have all been in the ‘closed’ tube. But it isn’t really closed. It is open on both ends.

I’m no longer bothered by the process but I can’t lie still for that long without wiggling! What helped me the most with the first one, was Ativan (lorazepam), a mild anti anxiety med. Ask your provider for a prescription. It comes in very small .5mg tabs. I was instructed to take 1 tab, an hour before the appt. Then another when I arrived.
The Ativan really took care of any anxiety I had about being claustrophobic. I was so relaxed (almost asleep) through the entire process. With my subsequent MRIs I’ve only taken small amount just to help me remain still.

During the imaging, if you ever want the technician to stop, all you have to do is let them know. You’re in constant communication with the tech via Ear buds. They ask frequently how you’re doing. Some facilities have a little squeeze ball you hold onto and if you have any qualms you squeeze the ball, the tech stops the scan!
They are also really nice about walking you through the process. They want you to know that they come immediately to help you get up if needed. From what I’ve learned, more of their patients are claustrophobic than not! Let the techs know because they spend extra time in reassuring you.

Have you considered a mild relaxant?
