目的 比较与分析CT与MRI用于 膝半月板和关节软骨损伤的诊断价值， 从而为患者临床诊断、治疗提供一定参 考。方法 将我院所收治的100例患者(其 中关节软骨损伤100个，半月板损伤98 个)作为本次研究对象，分别应用MRI与 CT检查，以关节镜检查为金标准，统计 两组临床检出率。结果 经研究发现， MRI组的软骨损伤Ⅳ期及半月板损伤Ⅲ 级检出率明细高于CT组，差异显著具有 统计学意义(P＜0.05)；然MRI临床检出 率与关节镜组相比较，差异无统计学意 义(P＞0.05)；然CT组软骨损伤Ⅳ期及 半月板损伤Ⅲ级检出率明细低于关节镜 检出率，差异显著具有统计学意义(P ＜0.05)。结论 应用MRI用于临床诊断膝 半月板和关节软骨损伤具有较高价值， 尤其是检测软骨损伤Ⅳ期及半月板损伤 Ⅲ级。

Objective Comparison and analysis of CT and MRI diagnostic value for the knee meniscus and articular cartilage damage, so patients for clinical diagnosis and treatment provide a reference. Methods A total of 100 patients in our hospital were taken as the clinical research objects (100 of which joint cartilage injury, meniscal 98). MRI and CT were applied to arthroscopy as the gold standard statistical groups clinical detection rate. Results The study found cartilage damage and meniscal Ⅲ Ⅳ grade of MRI detection rate is higher than the CT group detail group, significant difference was statistically significant (P<0.05). however clinical MRI detection rate and arthroscopic group compared to no significant difference (P>0.05). however CT group and meniscal cartilage injury ⅳ ⅲ level of detail below the detection rate arthroscopy out rate, a significant difference was statistically significant (P<0.05). Conclusion MRI for clinical diagnosis of the knee meniscus and articular cartilage damage with a higher value, especially the detection of cartilage damage and meniscal tear Ⅲ Ⅳ grade.
