[Accuracy of magnetic resonance (0.5 T) in traumatic lesions of the knee. Controlled 87 cases].
In this study the authors investigated the diagnostic accuracy of Magnetic Resonance (MR) imaging as a method to recognise traumatic disorders of the knee; in particular its capability to identify meniscal and cruciate ligaments tears was examined. The results have been compared with those from arthroscopy and/or surgery, which were considered the gold standard of the study. Eighty-seven consecutive patients with suspected traumatic injury of the knee were prospectively studied. All patients underwent MR examination (0.5 Tesla magnet, gradient echo sequences, slices thickness = 5 mm) and, within 15 days/1 month, arthroscopy or surgery. The high diagnostic accuracy (internal meniscus = 87.5%; external meniscus = 88.5%; anterior cruciate ligament = 93.1%; posterior cruciate ligament = 96.5%) has confirmed the good diagnostic capabilities of MR in assessing traumatic lesions of the knee.
