So what are youl nervous about? Are you claustrophobic? If so you can ask to have an open MRI. You could ask to be put to sleep. They have short acting sleep medications available or you might ask your doctor for a tranquilizer. There are certain medical health conditions where an MRI may not be recommend, Epilepsy, which is my nemesis, being one but I’ve had at least 4 with no problems. I’d rather have. You could ask if a CT would be appropriate in your condition although CT’s use radiation. There are about 40 million MRI’s done in every year.
