摘　　要：目的：通过分析肾细胞癌的双源多层螺旋 CT 征象与病理之间的关系，探讨双源多层螺旋 CT 对肾细胞癌的诊断价值。方法回顾性分析经手术病理证实的129例肾细胞癌患者的 CT 表现，依据2004年最新 WHO 病理分型，将 CT 征象与手术病理进行对照分析。结果肾癌细胞排列方式与增强效果之间存在相关性；肿瘤周边的短毛刺征与病理中肾包膜有无侵犯呈正相关；肾细胞癌 CT 的 Robson 分期与病理分期具有很好的一致性（Kappa=0.75）。结论肾细胞癌的 CT 征象与病理类型和肿瘤内部结构有关，双源多层螺旋 CT 对肾细胞癌的诊断有重要临床价值。Objective To analyze relationship between dual-source MDCT and pathology in renal cell carcinoma.Methods 129 patients with pathology were proved renal cell in our hospital from 2009 to 2012.According to the latest 2004 WHO pathological classification,CT features of renal carcinoma were compared with surgical and pathological results.Results The enhancement de-gree of lesions on contrast CT was correlated to the modal of renal malignant cells’ranking.There was no certain correlation be-tween integrity on the edge of the tumor in CT and pathological tumor capsular.The short-hair sign surrounding the margin of tumor strongly indicated renal capsule invasion （P 〈0.01）.Agreement between CT-Robson staging and surgical-pathologic staging was good（Kappa=0.75）.Conclusion The CT finding of renal cell carcinoma is correlated with tumor cell characteristic and inter-nal structure.Dual-source MDCT has important clinical value in the diagnosis of renal cell carcinoma.
