Helical CT Scan:the Value in the Diagnosis of Small Renal Cell Carcinoma / 实用放射学杂志

ABSTRACT

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.
