| 摘 要： | 目的分析肾细胞癌(renalcell carcinoma,RCC)常见病理亚型的多层螺旋CT(MSCT)表现,旨在提高对RCC各亚型的CT诊断及鉴别诊断水平。资料与方法回顾性分析经手术及病理证实的165例RCC患者的临床及影像资料。所有病例均行MSCT平扫和增强扫描。评价指标包括3种RCC亚型的性别差异、CT平扫和多期增强表现以及周围侵犯和远隔转移等。采用盲法评价,并对其间差异进行统计学分析。结果 3种亚型肿瘤的形态、密度、钙化、强化程度、形式和动态变化等表现的差异均有统计学意义(P<0.05)。其中,透明细胞癌形态常不规则,密度不均,皮质期(CP)呈不均匀明显强化且实质期(NP)强化程度明显减低。此外,局部侵犯和远隔转移的发生率也高于非透明细胞癌。乳头状癌和嫌色细胞癌发生钙化的比率均显著高于透明细胞癌,增强扫描常表现为CP轻度强化和NP强化增高,且增强各期净增CT值均显著低于透明细胞癌。乳头状癌与嫌色细胞癌相比,仅前者表现密度不均、强化不均匀的比例显著高于后者。其他评价指标包括性别和肿瘤大小等,在3种亚型肿瘤间差异无统计学意义(P>0.05)。结论 MSCT对诊断和鉴别诊断透明细胞癌与非透明细胞癌有重要意义... |

| Abstract: | Objective To discuss multislice CT(MSCT) appearance of common pathologic subtypes of renal cell carcinoma(RCC),and improve its diagnostic accuracy.Materials and Methods The clinic data and MSCT findings of 165 cases with RCC proved by operation and pathology were retrospectively analyzed.All the cases were performed with plain and contrast CT scan.The evaluating indexes included sex predilection,CT manifestations,adjacent infiltration,metastasis and so on.Double blinding method and statistic analysis among ... |
