Well , Brendan's point is a good one: that the doctors or the MRI people should give a heads up to patients if there are going to be head restraints. As his post noted, having it sprung on you could be unnerving. I noticed that the Main OCF forum has this to say on Eileen's point
[quote]If you have had fears of being confined in a small space (claustrophobia), you may find magnetic resonance imaging (MRI) to be frightening. This scan requires being placed in a small cylinder surrounded by a large, noisy machine. About 20 percent of people find it hard to tolerate, and about 5 percent are unable to go through with it. There are ways to make it easier today, such as listening to music or relaxation tapes or taking a medication to reduce your anxiety during the procedure. Tapes with instructions for relaxation, guided imagery, and medication can be listened to ahead of time to help you become calmer. [/quote]
