Magnetic resonance imaging(MRI) is accepteci as an useful tool for the diagnosis of injury of the knee recently. To evaluate the usefulness of MRI in the diagnosis of acute cruciate ligament tears, 28 cases of accute cruciate, ligament injuries(12 cases of anterior cruciate ligament(ACL) tears, 13 cases of posterior cruciate ligament(PCL) lears, and 3 cases of both ligament tears) were retrospectively reviewed with confirmatory tool of arthrotomy and arthroscopy. We applied 3 direct and 4 indirect MR criteria for ACL tears, and 2 direct MR criterial PCL tears. The results were as follows; I. The accuracy of direct signs for ACL teats was 85.7%(sensitivity, 93.37%, specificity, 76.99% ). 2. The accuracy of direct signs for PCL tears was 89.3/I(sensitivity, 93.8; specificity, 83.3% ). 3. The accuracy of indirect signs for ACL tears was 71.4%(sensitivity, 93.3%.; specificity, 46.2%). 4. The speciticity of MRI for the diagnosis of ACL tears was incrcased with direct signs combining with indirect signs ( l00% in combination of direct sign with 2 or more indirect signs). 5. The diagnosis of ACL tears was more difficult than that of PCL, tear because of its thin and oblique course compared to PCL. 6. T2-weighted image wa more helpful than T1-weighted image in the diagnosis of ligament tears. In conclusion, MRT is an useful tool for thc diagnosis of acute cruciate ligament tears. And the speciticity of MRI for the ctiagnr>sis of ACL lears was increased with direct signs combining with indireci signs.
