摘要
目的探讨螺旋CT在诊断小肾癌中的价值。方法对螺旋CT诊断的31例小肾癌患者的影像学特征进行回顾性分析,并与临床手术病理结果进行对比。结果螺旋CT诊断的31例患者,29例经术后病理证实,螺旋CT诊断的准确率为93.5%(29/31);将2例错构瘤误诊为小肾癌。典型影像学表现:小肾癌螺旋CT平扫多数呈圆形或类圆形等低密度肿块;增强扫描皮质期一过性均匀或不均匀显著强化,实质期强化迅速减退,呈"快进快退"的强化特征。结论螺旋CT尤其是增强扫描是诊断和鉴别小肾癌较准确、可靠的方法,具有重要的临床价值。
Objective To investigate the application of Spiral CT in the diagnosis of small cell renal cell carcinoma. Methods The imaging characteristics of spiral CT were analyzed retrospectively in diagnosis of 31 cases of small renal cell carcinoma and compared to clinical surgical and pathological findings. Results By surgery and pathology, 29 cases have been diagnosed for small renal cell carcinoma among 31 patients. Spiral CT diagnostic accuracy was 93.5 ~ （29/ 31） ; 2 cases of hamartoma was misdiagnosed as small renal cell carcinoma. Typical imaging performance： the small renal cell carcinoma spiral CT scan the majority were round or oval low-density mass~ enhanced scan cortex over homogeneous or inhomogeneous significantly enhanced, in real terms of enhanced rapid decline was fast washing enhancement pattern of retreat. Conclusion Spiral CT enhanced scan is more accurate and reliable method of diagnosis and differential diagnosis of small renal cell carcinoma, it has an important clinical value.
