摘　　要：目的﹐探讨在透明细胞软骨肉瘤(CCCS)的诊断中应用核磁共振成像(MRI)的准确性及影像学特点.方法︰研究纳入华君医院收治的疑似CCCS患者71例,患者的就诊时间为2018年5月-2020年5月。依次给予所有患者MRI检查和计算机断层扫描(CT)检查,以病理检查结果为诊断标准,探讨MRI检查的诊断价值,并且总结患者的影像学特点。结果﹐CT检查的确诊率为87.32%,MRI检查的确诊率为91.55%。MRI检查的敏感性,特异性以及阴性预测值均高于CT检查,差异有统计学意义(P<0.05);经MRI检查CCCS患者骨质破坏情况主要体现在溶骨性破坏(78.46%),部分患者存在侵蚀性破坏(21.54%);在钙化类型方面主要体现在点状钙化(100.00%),同时伴有明显的不均匀的分隔状强化(100.00%)和混杂信号(81.54%)。结论MRI对CCCS的诊断准确性明显高于CT检查,并且其主要的影像表现体现在不均匀的分隔状强化.溶骨性破坏、点状钙化和混杂信号及几个方面,临床诊断价值显著。Objective To investigate the accuracy and imaging characteristics of Magnetic resonance imaging(MRl)in the diagnosis of clear cell chondrosarcoma(CCCS).Methods A total of 71 suspected CCCS patients inour hospital were studied,and the treatment time was from May 2018 to May 2020.All patients were given MRIexamination and computed tomography(CT)examination in turn.Taking pathological examination as goldenstandard,the diagnostic value of MRl was evaluated and the imaging characteristics of patients were summarized.Results The diagnostic rate of CT,MRl and gold standard were 87.32%and 91.55%.The sensitivity,specificityand negative predictive value of MRl were significantly higher than those of CT examination(P<0.05).The bonedestruction of CCCS patients was mainly distributed in ostcolytic destruction(78.46%),and some patients had erosivedestruction(21.54%).In terms of calcification types,it was mainly reflected in punctate calcification(100.00%).accompanied by obvious uneven septate strong(100.00%)and mixed signal(81.54%).Conclusion The accuracy of MR1 in the diagnosis of CCCS is significantly higher than that of CT,and the main imaging manifestations of cCcsare inhomogeneous septal enhancement,osteolytic destruction,punctate calcification and mixed signal and severalaspects,which has significant clinical diagnostic value.
