【摘要】 目的探讨对甲状腺血流信号丰富程度进行量化在诊断中的价值。方法甲状腺功能亢进(甲亢)患者30例,以彩色直方图测量并自动计算取样区内彩色血流面积与取样区总面积的比率(blackandwhitecolorratio,BCR),并与30例正常人对比。结果甲状腺动脉的血流动力学参数中,加速度(Acc)、加速度时间(Act)、最大流速(Vmax)和彩色血流面积与取样区面积比率(BCR)明显高于正常对照组(P<0.001)。而甲亢组BCR与Vmax以及BCR与血清T3之间,并无明显线性关系(P>0.05)。结论彩色直方图可作为甲亢首选的筛选方法。更多还原

【Abstract】 Objective To evaluate the diagnostic value for planty degree of thyroid gland blood flow signals quantified by color histogram.Methods In thirty patients with hyperthyroidism the ratio of the area of the color information part inside the ROI to the total area of the ROI were measured and autocalculated by color histogram(Black and white color ratio,BCR).Thirty normal cases were as the control group.Results The hemodynamics parameters of the thyroid arteries(Acc,Act,Vmax) and BCR were markedly higher than those in the normal control group (P<0.001).However,relationship between BCR and Vmax,BCR and serum T3 were not linear (P>0.05) in the hyperthyroidism group.Conclusions Color histogram can be used as a first-line screening method for hyperthyroidism.更多还原
