Hi laidback,

If the only thing holding you back from having the MRI is your claustrophobia, how would you feel about seeking out a facility that offers an open MRI? You will still have to endure the noise but ear plugs can help and are often provided by the facility. There are various types of "open" MRI equipment. Some look something like a C clamp, some are stand-up or sit up style.

Something you might want to consider.
