Ask your provider. While open MRI can be an option, the magnet is much weaker than closed mri. This means the picture quality is not as good, like the difference between an inexpensive camera and a professional one. For some areas of the body, the open is okay. For others (spine in my practice) the higher quality is critical. Sedation can be used to deal with claustrophobia. Your provider can guide you.
Open MRI/ativan. There are some "open mri's" which can be a little more comfortable if you're claustrophobic. If you live in a rural area or aren't near one, sometimes primary care doctors give a pill like Ativan (lorazepam) to help you relax right before getting the scan. I'd ask your primary doctor about it. Good luck!
