【摘要】 目的　评价彩色多普勒能量图 (CDPI)对甲状腺结节病变良恶性鉴别诊断的价值。方法　对 3 3例甲状腺结节病变患者 ,共 48个结节进行CDPI检查 ,做半定量分析 ,与术后病理进行对比分析。结果　甲状腺良性结节一部分无血流显示 ,显示血流的则周边部血流丰富 ,内部少血流 ,甲状腺癌 10 0 %可以探查到内部血流 ,且多数分布零乱 ,走行杂乱 ,显示出与良性结节的丰富血流间细微的差异。结论　甲状腺结节能量图的半定量分析有助于鉴别结节的良恶性更多还原

【Abstract】 Objective To evaluate the application of CDPI in differentiating malignant and benign thyroid nodules. Methods Thirty three thyroid nodule patients with 48 nodules were examined by CDPI.Final diagnosis of all the patients was contrast analyzed with half quantitative analysis and pathology after operation. Results A portion of benign thyroids had no blood stream to show,while the nodules showing blood stream had peripheral rich blood stream and few blood streams inside them.All of thyroid cancers were found intralesional vascularization,anarchical structure and winding vessel caliber,which showed the subtle difference with the rich intralesional blood flow of benign nodules.Conclusion The half quantitative analysis of the CDPI of thyroid nodules is helpful in differentiating malignant and benign thyroid nodules.更多还原
