| 摘 要： | 目的探讨CT多期增强扫描在肾细胞癌诊断中的应用价值。方法分析经手术病理证实的38例肾细胞癌患者,男27例,女11例,年龄25～72岁(平均48岁)。全部采用CT多期增强扫描。结果均为单肾单发病灶,形态上呈圆形或椭圆形35例,形态不规则3例;有明显假包膜26例(68%);密度呈较均匀稍低密度27例(71%);31例(82%)肿瘤呈重度强化,5例(13%)呈中度强化,2(5%)例呈轻度强化。35例(92%)强化不均匀。95%的病灶强化均呈"快进快出"型。CT分期准确率为95%。结论CT多期增强扫描是肾癌术前诊断与鉴别诊断的有效方法。

| Abstract: | Objective To evaluate the characteristic appearances of RCC in dual-phase helical CT study.Methods Dual-phase helical CT findings in 38 cases(27 male,11 female)with RCC proved by surgical and pathological specimens were analyzed retrospectively.Results 26 cases(68%)showed pseudocapsule and 35 cases(92%)showed clear shape;On the precontrast scan,RCC appears slightly-hypodensity in 27 cases(71%);on post contrast scan,homogeneous enhancement were found in 35 cases(92%);31 cases(82%)showed significant enhancement,5 cases(13%)showed moderate enhancement,2 cases(5%)showed mild enhancement.95% of the cases showed strong enhancement in the cortical phase but weak enhancement in the late phase.Conclusions The multi-phase helical CT scan is useful for the diagnosis and staging of RCC. |
