Comparative study of dual-source MDCT signs with pathology in renal cell carcinoma / 实用放射学杂志

ABSTRACT

Objective To analyze relationship between dual-source MDCT and pathology in renal cell carcinoma.Methods 129 patients with pathology were proved renal cell in our hospital from 2009 to 2012.According to the latest 2004 WHO pathological classification,CT features of renal carcinoma were compared with surgical and pathological results.Results The enhancement de-gree of lesions on contrast CT was correlated to the modal of renal malignant cells’ranking.There was no certain correlation be-tween integrity on the edge of the tumor in CT and pathological tumor capsular.The short-hair sign surrounding the margin of tumor strongly indicated renal capsule invasion (P <0.01).Agreement between CT-Robson staging and surgical-pathologic staging was good(Kappa=0.75).Conclusion The CT finding of renal cell carcinoma is correlated with tumor cell characteristic and inter-nal structure.Dual-source MDCT has important clinical value in the diagnosis of renal cell carcinoma.
