彩色多普勒能量图与彩色多普勒血流图在肾肿瘤诊断中的作用

目的 :比较 CDE和 CDFI在肾肿瘤诊断中的作用。方法 :分别用 CDE和 CDFI显像各种肾肿瘤 5 1例 ,分析不同肿瘤的血流供应特征 ,并比较 CDE和 CDFI的显像优劣性。结果 :CDE显示 97.2 %的肾细胞癌血流丰富 ,其中 级血流占 80 .5 % ,且 5 0 %出现异常血流形态。而肾盂癌和肾良性肿瘤血流分级均为 0～ 级 ,血流形态单一 ,与肾细胞癌明显不同 (P<0 .0 1)。 5 2 .9%的肿瘤血流显示 CDE>CDFI,47.1% CDE=CDFI,无 1例 CDE

The Role of Color Doppler Energy and Color Doppler Flow Imaging in the Diagnosis of Renal Neoplasm

Objective:To compare the roles of color Doppler energy (CDE) and color Doppler flow imaging(CDFI)in the diagnosis of renal neoplasm.Methods:Fifty one cases with different kinds of renal neoplasm were examined by CDE and CDFI.The blood supply characteristics of renal neoplasm and the showing ability of CDE and CDFI were studied and compared.Results:92 7% renal cell carcinomas showed high blood perfusion,80 5% of them were high grade perfusion,50% of them appeared abnormal blood pattern;but all the benign renal tumors were low grade perfusion and their blood patterns were much different from that of renal cell carcinoma( P <0 01).CDE is excellent than CDFI in 52 9%,CDE is equal to CDFI in 47 1%.The sensitivity of CDE is significant different of CDFI.Conclusion:CDE may nicely distinguish the malignant renal neoplasm to benign tumor,and its showing ability of the blood flow of renal neoplasm is superior to CDFI.
