摘要
[目的]探讨三维能量多普勒超声诊断良恶性甲状腺肿瘤中的诊断价值。[方法]回顾性分析2011年5月至2015年7月本院收治的76例经手术或病理确诊为甲状腺肿瘤患者的临床资料，所有患者入院后均已接受三维能量多普勒超声检查，且影像学资料完整，观察良恶性甲状腺肿瘤血流特点，评定三维能量多普勒超声在甲状腺良恶性肿瘤鉴别中的价值。[结果]①良性甲状腺肿瘤患者灰阶值（MG）高于恶性患者（P〈0．05），血管化指数（Ⅵ）、血流指数（FD、血管化血流指数（VFD低于恶性肿瘤患者，其差异有统计学意义（P〈0．05）；②良、恶性甲状腺肿瘤血流分级Ⅱ级所占比例比较差异无统计学意义（P〉0．05），良性肿瘤患者血流Ⅰ级所占比例明显高于恶性者，Ⅲ级所占比例低于恶性者，其差异有统计学意义（P〈0．05）；③良性甲状腺肿瘤血流分布外周所占比例、血管规则走行比例及空间分布对称比例均高于恶性肿瘤者，其差异有统计学意义（P〈0．05）；④三维能量多普勒超声检出良性甲状腺肿瘤31例，其中29例确诊，2例误诊；恶性45例，其中40例确诊，5例误诊，其整体诊断符合率为90．79％（69／76）。[结论]采用三维能量多普勒超声诊断甲状腺良恶性肿瘤，与病理诊断符合度高，可清晰显示肿瘤血流分布、血管特点及内部结构，且操作简单、无创，值得临床推广应用。
[Objective]To explore clinical value of three dimensional （3D） power Doppler ultrasound in the diagnosis of benign and malignant thyroid tumors. [Methods] A retrospective analysis of clinical data was carried out in 76 patients with thyroid tumors confirmed by operation or pathology in our hospital from May 2011 to July 2015, all patients had received three dimensional power Doppler ultrasound examination after admission, and the imaging data were complete, features of blood flow of benign and malignant thyroid tumors were observed, and diagnostic value of three dimensional power Doppler ultrasound for thyroid benign and malignant tumors were evaluated. [Results] 1）Gray scale values （MG） of patients with benign thyroid tumors were significantly higher than patients with malignant thyroid tumors （ P 〈0.05）, the vascular index （Ⅵ）, blood flow index （FI） and vascular blood flow index （VFI） were significantly lower than those with malignant tumor （ P 〈0.05） ; （2）there was no significant difference in the proportion of blood flow grading grade Ⅱ in benign and malignant thyroid tumors （ P 〉0.05）, the proportion of grade Ⅰ in patients with benign tumors was significantly higher than that of the malig- nant , and the proportion of grade In was significantly lower than that of the malignant （ P 〈0.05） ; （3）the proportion of peripheral blood flow distribution , the vascular rule and the spatial distribution symmetry in benign thyroid tumors were significantly higher than those with the malignant （ P 〈0.05） ; （4）31 cases of benign thyroid tumors were detected by 3D power Doppler ultrasound, including 29 cases confirmed and 2 cases misdiagnosed; 45 cases of malignant tumors, among which 40 cases were confirmed and 5 misdiagnosed , and the overall diagnostic accordance rate was 90.79%（69/76）. [Conclusion] The diagnosis of benign and malignant tumors of the thyroid gland with three-dimensional power Doppler ultrasound is in good agreement with the pathological diagnosis, which can clearly show the tumor blood flow distribution, vascular characteristics and internal structure. The operation is simple without wound, it is worth clinical application.
