The diagnostic accuracy and clinical utility have been evaluated of 2810 consecutive magnetic‐resonance‐imaging examinations that were performed on a 1.5‐T Signa magnetic‐resonance‐imaging unit at The Royal North Shore Hospital of Sydney between November 1986 and December 1987. The average accuracy of magnetic resonance imaging was 80%, and ranged from 21%–98% in various brain‐disease and spinal‐disease categories, compared with the average provisional premagnetic‐resonance‐imaging diagnostic accuracy of 64%, and an average accuracy of computed tomography of 45%. Clinical follow‐up at three months after magnetic‐resonance‐imaging investigation indicated that, as a result of the magnetic‐resonance‐imaging examination, patient management was altered in 70% of cases, and patient outcome was altered in 62% of cases.
