目的：探讨磁共振和64排螺旋CT对膝关节外伤的诊断价值对比。方法选取65例于2014年10月—2015年10月期间该院接收的膝关节外伤患者,均行磁共振和64排螺旋CT扫描,观察两者的检查结果。结果磁共振膝关节外伤检出率为98.5%高于64排螺旋CT的90.8%(P<0.05),且磁共振在半月板损伤、骨质损伤、韧带损伤、关节积液上的诊断准确率分别为100%、96.0%、100.0%、100.0%,64排螺旋CT分别为95.5%、92.0%、75.0%、90.0%,但除半月板损伤外,组间比较差异无统计学意义(P>0.05)。结论膝关节外伤采用磁共振和64排螺旋CT检查,均可有效诊断,但磁共振的诊断效能更佳。%Objective To discuss and compare the value of magnetic resonance and 64 slice spiral CT in diagnosis of knee joint injury. Methods 65 cases of patients withknee joint injury treated in our hospital from October 2014 to October 2015 were selected and were given magnetic resonance and 64 slice spiral CT scanning, and the examination results were ob-served. Results The detection rate of magnetic resonanceis higher than that of 64 slice spiral CT in diagnosis of knee joint injury,(98.5% vs 90.8%)(P<0.05), and the accuracy rate of magnetic resonance in diagnosis of meniscus injury, bone in-jury, ligament injury and hydrops articuli was respectively 100%, 96.0%, 100.0%and100.0%, and the accuracy rate of 64 slice spiral CT in diagnosis of meniscus injury, bone injury, ligament injury and hydrops articuli was respectively 95.5%, 92.0%,75.0% and 90.0%,but there was no difference between groups by comparison except the meniscus injury (P>0.05). Conclusion Both magnetic resonance and 64 slice spiral CT can effectively diagnose the knee joint injury,, but the diagno-sis effect of magnetic resonance is better.
