【摘要】 目的：评价ＣＴ扫描在小肾癌诊断中的应用价值。方法：回顾性分析１１例经手术病理证实为小肾癌（直径＜ ３．０ ｃｍ ）的Ｂ超和ＣＴ资料。结果：１１ 例小肾癌病人中Ｂ超诊断肾囊肿２例、肾良性肿瘤１ 例、肾实性占位８例；ＣＴ诊断畸胎瘤１例、肾脏恶性肿瘤１０例。ＣＴ表现：①ＣＴ平扫为软组织密度结节、无钙化及脂肪组织１０例；②增强扫描显著强化１０例（△ＣＴ值＞ ４０ ＨＵ）；③肿瘤—肾实质界面模糊不清６例、清晰而不锐利４例。结论：ＣＴ检出小肾癌优于Ｂ超，根据小病灶的密度、边缘及强化程度等特征性ＣＴ表现术前能诊断为小肾癌。更多还原

【Abstract】 Objective:To evaluate the value of CT scan in diagnosis of small renal carcinoma.Methods:The US and CT scan datum of 11 paients pathologically proved renal cell carcinomas(3 cm or less in diameter)were retrospectively analyzed.Results:Of 11 cases,renal cyst(2 cases)benign renal tumor(1 case)and solid mass(8 cases)were diagnosed by US,while.Maligant renal tumors(10 cases)and teratoma(1 case) were diagnosed by CT scan.CT manifestations were as follow:①a renal mass of soft tissue attenuation without calcifications and fats(10 cases),②the lesion obvlous enhanced (10 cases),③an indistinct mass-parenchymal interface (6 cases)and a clear-cut lesion without sharp edge(4 cases).Conclusion:CT scan is superior to US in the ability detecting small renal cell carcinomas.Based on CT features,diagnosis of malignant small renal tumors may possibly be established betore operation.更多还原
