摘 要:目的 探讨彩色多普勒能量图(CDE)和彩色多普勒血流显像(CDFI)甲状腺,对良恶性肿瘤鉴别的意义。方法对56例甲状腺肿瘤患者(良性31例,恶性25例)行 CDE和 CDFI研究,了解肿瘤内部的血流显示与分级情况。结果其血流显示率在 CDE和 CDFI中分别为 82.l%和 57.l%,CDE较 CDFI提高 25.0%(P<0.05)。 CDE对肿瘤血流分级的显示55.4%优于 CDFI,44.6%与 CDFI相同,有显著差异(P<0.01)。根据 CDE与 CDFI中血流分级情况判断肿瘤良恶性,其鉴别诊断率分别为82.1%,85.7%。二者无显著差异(P>0.05)。结论CDE在甲状腺肿瘤血流的敏感性和准确性显示上优于CDFI,但二者对肿瘤良恶性的鉴别意义无大差别。Objective To compare the effectiveness between the funchon of Colour Doppler Energy (CDE) and that of colour Doppler Flow Imaging (CDFI) of the flowing images in thyroid tumor and to reveal the significance of CDE and CDFI in the diagnosis of benign and malignant tumors. Methods Fifty and six cases of thyroid tumor (31 benign and 25 ma- lignant cases) were studied. Results The flowing indication rate of 56 cases was 82.l% in CDE and 57.1% in CDFI;the former was 25.0% higher than the latter (P<0.05). The CDE indication of nowing classification of tumor was better than that of CDFI in 55.4%, and the same in 44.6%. which disclosed that the difference was obvious and great (P<0.01). By flowing classification, the diagnostic rate of distinguishing benign or malignant tumor was 82.l% in CDE and 85.7% in CDFI respectively; the deference was insignificant (P>0.05 ). Conclusion As to the sensitiveness and accuracy, CDE is better than CDFI in the flowing indication of thyroid tumor, but there is no great difference in distinguishing benign tumor from malignant one.
