Therein lies the problem. Panic/anxiety/claustrophobia are completely irrational and defy all logical advice. I know, I was there. Open MRI’s still don’t offer the same quality images. Neuro resident ordered oral Ativan, staff neuro said nope, IV the best way to go, especially when time is important. Given time and good counseling, I think many of us phobics can learn to deal with our irrational fears, but that’s not always possible or practical. Bottom line, you can do it.
Being in tight confining spaces and being nervous about it isnt necessarily irrational. there are plenty of valid reasons it makes people uncomfortable.
And given that devices like ct scanners which can also be claustrophobic, can go out of calibration when not maintained properly, people have been hurt by xray burns from them. Compound that concern with the tight space.
