摘要： 目的 探讨MRI在测量甲状腺体积中的临床应用价值。方法 对51例健康成人甲状腺行MRI扫描，采用T1WI、T2WI加权成像技术进行扫描，利用工作站对甲状腺体积进行测量，并对男性、女性甲状腺左右叶的差异进行统计学分析。结果 ⑴51例健康成人甲状腺体积为（14.297±5.440） cm3，其中甲状腺右叶体积为（7.395±2.858） cm3，左叶体积为（6.912±2.656） cm3， 两者体积差异无统计学意义（P＞0.05）；⑵男性（n=26）甲状腺总体积大于女性（n=25）甲状腺总体积，差异有统计学意义（P＜0.05）；⑶男性甲状腺左叶、右叶体积均大于女性甲状腺左叶、右叶体积，差异均有统计学意义（P均＜0.05）。结论 MRI可无创性测量甲状腺体积，通过分析不同性别甲状腺体积差异，可为临床判断甲状腺病变及临床手术评估提供参考依据。

Abstract: Objective To investigate the value of MRI for measuring thyroid volume. Method Thyroids of 51 normal adults were scanned by MRI using T1WI-and T2WI-weighted imaging technology. Volumes were compared for the left and right thyroid lobes and for the two genders. Results Mean total thyroid volume was（14.297±5.44） cm3；mean volume was similar for the right lobe （7.395±2.858） cm3 and left lobe （6.902±2.656） cm3；P>0.05）. Total thyroid volume was significantly greater in men（n=26）than in women（n=25，P<0.05）. Comparing the left lobe with right lobe between men and women，the volume of bilateral lobe volume in men was significantly larger than those in women. The difference was statistically significant（P<0.05）. Conclusion MRI may allow noninvasive measurement of thyroid volume，and the results suggest the need to take into account gender differences in thyroid volume when making treatment decisions.
