Abstract:
PURPOSE: This study is for the evaluation of low tesla(0.064T) MR imaging diagnostic accuracy in the internal derangement of the knee. MATERIALS AND METHODS: We retrospectively analysed the MR images of 36 injured knees of 35 patients. The presence of tear was determined by arthroscopy or surgery in all cases. RESULTS: The sensitivity, specificity, accuracy, positive predictive value, negative predictive value of low tesla MRI for the diagnosis of anterior cruciate ligament injury were 83%, 88%, 86%, 77%, 91%, for the posterior cruciate ligament 75%, 95%, 86%, 92%, 83%, for the medial collateral ligament 83%, 96%, 92%, 91%, 92%, for the lateral collateral ligament 67%, 97%, 94%, 67%, 97%, for the menisci 75%, 93%, 89%, 75%, 93%. CONCLUSION: The low tesla MRI is an accurate method in detection and evaluation of the internal derangement of the knee.
