目的比较CT和MRI诊断膝半月 板和关节软骨损伤的临床检出率，并讨 论其临床诊断参考价值。方法 回顾性比 较分析本院于2013年9月-2014年6月期间 收治因膝半月板和关节软骨损伤而进行CT 及MRI检查诊断且图像特征典型、清晰的 患者150例(关节软骨损伤152个，半月板 损伤149个)的临床检出率，并分别与关节 镜检查的检出率相比较，同时进行统计 学分析。结果 观察组软骨损伤Ⅳ期和半 月板损伤Ⅲ级的临床检出率显著高于对 照组(P＜0.05)，差异具有统计学意义， 而与关节镜检查的检出率差异不显著(P ＜0.05)。对照组软骨损伤Ⅳ期和半月板 损伤Ⅲ级的临床检出率显著低于关节镜检 查的检出率(P＜0.05)，差异具有统计学 意义。结论 MRI在诊断Ⅳ期关节软骨损伤 和Ⅲ级半月板损伤的临床检出率高于CT诊 断。

Objective To compare the clinical CT and MRI diagnosis of knee joint meniscus and articular cartilage injury detection rate, and discuss the clinical diagnosis value of reference. Methods Review the comparison and analysis of the hospital in 2013 September-2014 June hospitalized during the period because of knee meniscus and articular cartilage injury in 150 patients who underwent CT and MRI scan in the diagnosis and the image characteristics of typical, clear method (articular cartilage injury of meniscus injury in 152, 149) clinical detection rate and detection rate, respectively with arthroscopy in comparison, and carries on statistics analysis. Results the observation group cartilage injury clinical stage IV and meniscus injury grade detection rate was significantly higher than that of the control group (P<0.05), statistically significant differences with arthroscopy, the detection rate of no significant difference (P<0.05). Controlled clinical group IV and cartilage injury of meniscus injury grade detection rate was significantly lower than the detection rate of arthroscopy (P<0.05), with significant difference. Conclusion MRI in the diagnosis of stage IV and III articular cartilage injury of meniscus injury was higher than that of CT diagnosis.
