摘　　要：目的 分析肾癌的螺旋ＣＴ表现，探讨ＳＣＴ薄层多平面重建在肾癌诊断及分期中的价值。方法　 在３３例中利用ＳＣＴ薄层多平面ＣＴ征象所见与手术病理结果对照。结果　ＳＣＴ薄层多平面分期扫描显示最小肿瘤特征，Ⅰ期５例，Ⅱ期１０例，Ⅲ期９例，Ⅳ期９例，与手术病理对照，准确率为 ８７．８７％。结论 ＳＣＴ薄层及多平面重建的方法可准确显示肾癌的特征与邻近浸润及肾静脉与下腔静脉内癌栓表现，提高诊断与分期的符合率。Objetive To analyze spirl CT(SCT) features of ranal cell carcinoma, evaluate the role of thin - slice and multi - planar reconstruction (MRR) of SCT in the diagnosis and staging of renal cell carcinoma. Method The preoperative CT data of 33 case of ranal cell carcinoma were reviewed with comparative studies of operative and pathologic findings. Results The accurate rate of thin - slice and multi - planar reconstruction of spiral CT was 87.7%, Conclusion The way can well demonstrate the features of the lesion, invasion and carcinous embolus in the renal vein and inferior vena cava; it improve the accurate rate of diagnosis and staging of renal cell carcinoma.
