급성 및 만성 전방십자인대 손상의 진단에 대한 자기공명 영상과 관절경 검사의 비교 = The Correlation between Magnetic Resonance Imaging and Arthroscopy : Acute versus Chronic Tears of Anterior Cruciate Ligament

다국어 초록 (Multilingual Abstract)

76 magnetic resonance (MR) studies of the knee were reviewed to evaluate the diagnostic validity of MR imaging compared with the arthroscopic findings and to identify the'eharacteristic findings of acute versus chronic anterior cruciale ligament tears on MR imaging. The sensitivity, specificity, accuracy, negative predictive value and positive predictive value 84.2%, 90.0%, 86.2%, 94.1% and 75% respectively for acute anterior cruciate ligament tears and 86.4%, 100%, 93.6%, 100% and 89.3% respectively for chronic tears. In acute anterior cruciate ligament tears, MR imaging showed discontinuity with or without high signal intersity of the ligament, high signal intersity without discontinuity and high signal intersity at the lateral compartment of the knee on T2 images. In chronic tears, MR imaging showed discontinuity, irregular contour and attenuation of the bgament. High bone signal infersity on the )ateral compartment of the knee and high signal intersity in the anterior cruciate ligament were characteristic fmdings of acute anterior cruciate ligament tears.
