【摘要】 目的观察亚临床甲状腺功能减退症简称亚甲减CDFI与3DCPA的声像图特征，分析各参数与TSH、TPOAb的关系及在亚甲减诊断中的应用价值。方法 确诊亚甲减患者32例作为病例组，32例排除亚甲减患者作为对照组，CDFI条件下，采集甲状腺上动脉收缩期峰值流速(PSV)、阻力指数(RI)和达峰值流速时间(AT)，3DCPA条件下对甲状腺上动脉和腺体内感兴趣区进行观察分析，获得定量指标：平均灰阶(MG)、血管指数(VI)、血流指数(FI)和血流血管指数(VFI)，进行对比分析。并对各参数与促甲状腺激素(TSH)、甲状腺过氧化物酶抗体(TPOAb)等甲状腺功能指标作相关分析。结果 病例组CDFI及3DCPA表现与正常组明显不同。病例组患者的MG(42±4.15)、VI(18.29±1.86)、FI(32±2.1)VFI(9.6±0.80)、PSV(69.2±10.1 cm/s)、及AT(0.072±0.18 s)均较对照组MG(37±2.65)、VI(11. 7±0.102)、FI(24.05±1.56)及VFI(0.33±0.02)、PSV(69.2±10.1 cm/s)及AT(0.030±0.01 s)明显增高MG、VI、FI、VFI、PSV、及AT均明显高于对照组(P<0.05)，且VI、FI、VFI、PSV与TSH、TPOAb正相关，RI在病例组与对照组之间的差异无统计学意义。结论 CDFI结合3DCPA可以定性定量判定甲状腺腺体的回声水平和血流情况，可作为二维超声的有益补充，对正确诊断亚甲减和指导临床治疗具有重要意义。

【Abstract】 Objective To quantify Doppler signal in subclinical hypothyroidism(SHT)patients and provide quantitative parameters with threedimensional caor power angiography(3DPDA)and color Doppler flow imaging(CDFI). Then analysis the relationship between the above indices and TSH, TPOAb and TGAb. Methods Thirty two patients with SHT(case group)and thirty two normal controls(control group)were examined by 3DCPA and CDFI. Under the CDFI condition to exam Peak Systolic Velocity of Superior Thyroid Artery(PSV)and Resistive Index(RI)and Acceleration Time(AT). Meanwhile region of interested(ROI)were defined to obtain histogram and the quantification index:Mean Gray(MG), Vascularization Index(VI), Flow Index(FI), Vascularization Flow Index(VFI). Then analysis the relationship between the above indices and thyroid function parameters. Such as TSH and TPOAb. Results The difference between images of case group and control group was much significant. The quantification index MG(42±4.15),VI(18.29±1 ......
