【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。更多还原

【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.更多还原
