摘　　要：目的对比研究X线、CT三维重建对膝关节滑膜骨软骨瘤病临床诊断价值。方法选取本院2017年6月至2019年8月收治的45例确诊为膝关节滑膜骨软骨瘤病的患者作为研究对象,分析肿瘤大小、形态、密度、有无钙化等影像学特征,比较X线与CT三维重建对软骨关节、关节周围钙化结节、关节间隙深部钙化结节的显示情况。结果经整理45例患者临床资料共发现598个结节,其中软骨结节、关节周围钙化结节、关节间隙深部钙化结节分别有78个、507个、13个。X线未显示软骨结节,对关节周围钙化结节的显示率71.99%;CT三维重建对软骨结节、关节周围钙化结节的显示率分别为75.64%、99.80%,明显高于X线(P<0.05),两者对关节间隙深部钙化结节的显示率均为100%。结论X线与CT三维重建均可有效显示膝关节滑膜骨软骨瘤病的影像学特点,但CT三维重建对软骨结节、关节周围钙化结节显示更敏感,临床应用价值更广。Objective To compare and study the clinical diagnostic value of X-ray and CT three-dimensional reconstruction for synovial osteochondromatosis of the knee joint.Methods 45 patients diagnosed with knee synovial osteochondromatosis treated in our hospital from June 2017 to August 2019 were selected as the research objects.The imaging features such as tumor size,morphology,density,and the presence or absence of calcification were analyzed,and the X-ray and CT three-dimensional reconstructions were compared to display cartilage joints and calcified nodules around the joint and deep calcified nodules in the joint space.Results After collating the clinical data of 45 patients,a total of 598 nodules were found,including cartilage nodules,calcified nodules around the joint,and deep calcified nodules in the joint space,78,507,and 13,respectively.X-rays did not show cartilage nodules,and the display rate for the calcified nodules around the joint was 71.99%.The display rates of CT three-dimensional reconstruction for cartilage nodules and calcified nodules around the joint were 75.64%and 99.80%,which were significantly higher than those of the X-ray(P<0.05).Moreover,their display rates for deep calcified nodules in the joint space were both 100%.Conclusion X-ray and CT three-dimensional reconstruction can effectively show the imaging characteristics of synovial osteochondromatosis of the knee joint,but CT three-dimensional reconstruction is more sensitive to cartilage nodules and calcified nodules around the joints and has wider clinical application value.
