—The article by Mr Mélendez and Dr McCrank1 provides an excellent review of anxiety-related reactions associated with magnetic resonance imaging (MRI) examinations.However, missing from their review were some relevant articles2-4 that we came across in preparing our own ongoing study on anxiety-induced artifacts in MRI. Two of these studies2,3 were probably not known to the authors because they were published in European journals: one in German and the other in Italian (both, however, have English abstracts).We would especially like to draw your readers' attention to the study by Oberstein et al.2 With 21 633 subjects, it is by far the largest study so far published in this field. The results of this detailed study reveal two main obstacles that reduce the value of MRI routine examinations. First, an impaired tolerance to the investigation occurred in an average of 12% of cases
