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.
