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.
