摘　　要：1目的　比较 B超和 CT扫描在小肾癌诊断中的应用价值。 2方法　分析 11例经手术、病理证实为小肾癌的 B超和 CT资料。 3结果　 B超检出 9例 ,均为非囊性病变 ,但难以鉴别良、恶性 ;B超漏检 2例。CT检出10例 ,漏检 1例。明显强化的软组织密度结节及其边缘模糊不清等 CT征象能提示肿瘤为恶性。 4结论　 CT在检出小肾癌方面优于 B超 ,CT与Objective To compare the practical value of ultrasound(US) and computed tomography(CT) scanning in diagnosis of small renal cell carcinomas. Methods US and CT characteristic findings of 11cases of small renal cell carcinom as confirmed by surgery and pathology were analyzed. Results US dem onstrated noncystic lesion in9of the11cases and failed in differentiating benign and malignant lesions.CT(n=11) had true-positive results in ten cases and false-negative result in one.CT characteristic finding,such as enhanced soft-tissue mass and an indistinct mass-parenchymal interface,were helpful in the diagno- sis of malignancy. Conclusion CT was superior to U S in its ability to detect small renal lesions.CT combined with US is very useful for the correct diagnosis of small renal cell carcinoma.
