[摘要] 目的 探讨肾透明细胞癌多层螺旋CT的影像特征及与其他亚型的鉴别方法。 方法 回顾性分析2008年1月～2015年6月61例肾癌患者的CT图像，分成透明细胞癌组和非透明细胞癌组。比较两组增强幅度与肿瘤的大小、有无钙化、囊变、坏死和肿瘤的扩散状况(肾包膜、静脉及淋巴结转移)情况。 结果 平扫肾透明细胞癌组CT值和非透明细胞癌组CT值差异无统计学意义(P>0.05)。而皮质期和髓质期的透明细胞癌的CT值显著高于非透明细胞癌(P<0.05)。 结论 肿瘤的增强程度是鉴别肾透明细胞癌和非透明细胞癌最有价值的参数，而肿瘤的大小、有无钙化、囊变、坏死和肿瘤的扩散状况对鉴别有一定的作用。

    [Abstract] Objective To evaluate the image feature of multi-slice computed tomography(MSCT) in analyzing the different diameter renal clear cell carcinoma and the identification methods of various subtypes. Methods The enhancement degree of 61 cases pathology-proven renal clear cell carcinoma during biphasic contrast enhanced spiral CT scans from January 2008 to June 2015 were retrospective analyzed. The renal clear cell carcinoma patients were divided into two groups with clear cell carcinoma group (CCRCC group) and non-clear cell carcinoma group(non-CCRCC group). The correlation between enhanced extent and tumor size ......
