100 consecutive magnetic resonance imaging (MRI) examinations were rev
iewed independently by two radiologists. Patients were selected so tha
t the anatomical areas of clinical interest coincided with the special
interests of the reviewers. The reviewers were both consultant radiol
ogists, one with 3 years' and the other with 6 years' experience of MR
I. Hard copy images from the MRI examinations were reported independen
tly by both reviewers. Of the 100 MRI examinations, there was full con
cordance of opinion in 61/100. Of the remaining 39 cases, four (10%) w
ere considered ''minor unrelated'' differences, 12 (31%) ''minor relat
ed'' differences and 23 (59%) ''major related'' differences resulting
in a significant change in patient management.
