超微血管成像在甲状腺功能异常中的临床应用

目的应用超微血管成像探讨甲状腺上动脉血流参数（收缩期最大流速V_max、舒张期末流速V_min、阻力指数RI、血流量）在甲状腺功能异常的超声表现。 方法初次进行甲状腺检查的患者114例，根据血清检验结果，正常对照组84例，甲亢组34例，甲减组22例。使用方差分析比较3组甲状腺上动脉血流参数的差异，应用SNK比较法进行两两比较分析组间血流参数的差异。 结果正常对照组与甲减组的V_max（33.89±17.56 cm/s vs 68.23±15.41 cm/s）、V_min(12.31±7.59 cm/s vs 25.62±9.41 cm/s)以及血流量(14.92±10.61 mL/min vs 46.67±10.17mL/min)之间的差异有统计学意义（P<0.01），同时，比较甲减组与甲亢组的V_max(68.23±15.41 cm/s vs 38.36±16.61cm/s)、V_min(25.62±9.41 cm/s vs 14.15±7.06 cm/s)、血流量(46.67±10.17mL/min vs 14.63±9.69 mL/min )差异有统计学意义（P<0.01），3组间RI值差异无统计学意义（P>0.05），正常对照组与甲亢组的V_max、V_min、血流量差异无统计学意义（P>0.05）。 结论甲状腺上动脉血流参数作为定量参数，能反映甲状腺功能减低的血流情况。

Clinical application of superb microvascular imaging in thyroid dysfunction

ObjectiveTo explore ultrasound findings of the thyroid hemodynamic parameters in thyroid disorders by micro vascular imaging. MethodsFifty-six patients with untreated thyroid dysfunction and 84 in control group were enrolled. According to the results of serum tests, 56 patients were divided into hyperthyroidism group (n=34) and hypothyroidism group (n=22). The differences of vascularity index among the three groups were analyzed. ResultsThere were significant differences of Vmax（33.89±17.56 cm/s vs 68.23±15.41 cm/s）、Vmin(12.31±7.59 cm/s vs 25.62±9.41 cm/s) and vascularity flow (14.92±10.61 mL/min vs 46.67±10.17mL/min) in 3 groups (P<0.05). Resistive index in 3 groups had no significant differences. ConclusionThe hemodynamic parameters of thyroid can reflect the blood flow of hypothyroidism.
