In Reply.  —We are grateful to Dr Persili and colleagues for drawing our attention to three additional published articles concerning anxiety-related reactions during MRI examinations. We apologize for not having captured these references with our search strategy. The 12% incidence of "motor unrest or claustrophobia" reported by Oberstein et al1 is within the range found in our review. Of special interest was the correlation shown between final diagnosis and claustrophobic reactions in 21 633 subjects undergoing MRI examinations. This observation may be helpful in screening for subjects at risk. The article by Nozzolillo et al,2 based on 28 subjects, is also in keeping with findings reported in the publications reviewed in our article. The article by Ellis et al3 describes a handheld air bellows communication device that may be useful to facilitate patient communication during the test, though modern scanners have built-in voice communication systems.
