【摘要】 目的 评价螺旋CT在肾癌检查中的应用价值和肾癌CT征象与组织病理学的关系。方法 279例做了CT平扫及增强扫描,所有病例均经病理证实为肾癌。对肾癌的临床特征及CT表现与手术病理结果进行对照。结果 肾癌在CT增强扫描早期呈中度和显著强化者占90.32%,除颗粒细胞都为均匀强化外,其余细胞类型呈不均匀强化,32.26%肿瘤边缘有或多或少的短毛刺(χ~2=38.2,P<0.01),短毛刺征象与病理检查肾包膜侵犯有显著关系。CT定性诊断准确率为91.40%;CT分期与手术病理分期的相关系数为0.84;肾癌的CT分型与癌肿细胞类型没有明显相关性(P>0.05)。结论 多层螺旋CT能更好地显示出肿瘤的影像学特征,提高对肾癌的诊断准确性和分期能力。更多还原

【Abstract】 Objective To study the value of spiral CT in diagnosing renal cell carcinoma(RCC) and to evaluate the correlation of CT findings with histopathologic features in RCC.Methods 279 cases with RCC proven by surgery and pathology underwent plain and contrast-enhanced CT examinations.The clinic characteristics and CT findings were analyzed statistically and compared with surgical results.Results 90.32% lesions showed medium or obvious enhancement on contrast-enhanced CT,with the exception of granule cells for enhanced uniform,the other cell type of RCC showed heterogeneous enhancement.32.26% of tumors was of more or less short-burres(χ~2=38.2,P<0.01),and the there was significant relationship between pathological signs of short burr and the renal capsule involved by tumors.CT qualitative diagnostic rate was 91.40%.CT staging and pathologic staging were of the correlalive coefficient of 0.84,while there was not obviously correlation between CT classification of RCC and cancer cell types(P>0.05).Conclusion Spiral CT can better show characteristics of RCC,that can improve the diagnostic accuracy and staging aility for RCC.更多还原
