目的 对比CT与MRI增强扫描在透 明细胞软骨肉瘤中的诊断价值。方法 回 顾本院2015年5月-2017年5月就诊的94例 疑似透明细胞软骨肉瘤患者资料，随机分 为对照组47例，进行CT增强扫描；研究 组47例，进行MRI增强扫描。对比两组的 透明细胞软骨肉瘤确诊情况，透明细胞软 骨肉瘤的部位及形态、增强扫描征象。结 果 经检查，对照组有透明细胞软骨肉瘤 7例，研究组有透明细胞软骨肉瘤5例。两 组透明细胞软骨肉瘤均以股骨居多，形态 基本以叶状为主。对照组和研究组的透明 细胞软骨肉瘤均以溶骨性破坏、点状钙 化为主；对照组存在6例不均匀分隔状强 化，研究组5例都有不均匀分隔状强化。 结论 CT与MRI增强扫描在透明细胞软骨肉 瘤的临床诊断中均有明显的诊断价值，可 根据患者的实际情况灵活应用，提高诊疗 水平。

Objective To compare the diagnostic value of enhanced scanning of both CT and MRI in clear cell chondrosarcoma (CCCS). Methods The clinical data of 94 cases of suspected CCCS in our hospital from May 2015 to May 2017 were retrospectively analyzed. And patients were randomly divided into control group with CT enhanced scanning (n =47) and study group with MRI enhanced scanning (n=47). The diagnosis of CCCS, the location and morphology of CCCS lesions, and the scan signs were compared. Results The examination showed that there were 7 cases of CCCS in the control group and 5 cases in the study group. The lesions were mostly in femur, and were mostly presented with leaf shape. In both the control group and the study group, the CCCS were mainly dissolving bone destruction and punctate calcification. There were 6 cases of uneven separation enhancement in the control group and 5 cases in the study group. Conclusion CT and MRI enhanced scanning in the diagnosis of CCCS achieve obvious diagnostic value. The application is flexible according to the actual situation of patients, which can improve the diagnosis and treatment level.
