螺旋CT在小肾癌诊断中的价值

目的评价螺旋CT多期扫描在小肾癌诊断中的价值。方法收集经手术病理证实的小肾癌14例,分析其螺旋CT平扫、皮质期、实质期及肾盂期的表现。结果CT平扫病灶呈等密度7例,稍低密度5例,稍高密度1例,1例为囊实性肿块,其中2例伴斑点状钙化。增强扫描皮质期12例呈明显强化,2例呈轻中度强化。肾实质期肿瘤密度迅速减退,肾盂期肿瘤密度进一步减退。结论小肾癌螺旋CT增强多期扫描征象有一定特征性,对小肾癌的诊断有重要价值。

Helical CT Scan: the Value in the Diagnosis of Small Renal Cell Carcinoma

Objective To evaluate the value of helical CT scan in the diagnosis of small renal cell carcinoma.Methods The helical CT features of small renal cell carcinoma proved by operation and pathology in 14 cases were studied retrospectively.Results CT showedisodense mass in 7 cases,slightly low density mass in 5 cases,slightly hyperdense mass in 1 case,cystic and solid mass in 1 case,and among them 2 cases showed punctural calcification.The lesions showed marked enhancement in cortical phase in 12 cases,slight to moderateenhancement in 2 cases,in parenchymal phase,the tumor density dropped promptly,and in the pelvic phase the tumor density droppedfurther. Conclusion Small renal cell carcinoma is of certain characteristic on multi-phasic spiral CT contrast-enhanced scan,it is a very valuable method in diangosis of small renal cell carcinoma.
