不同性别正常人颞叶体积的MRI测量

MRI Measurements of Temporal Lobe Volume in Normal People with Different Gender

目的确定不同性别正常成人颞叶体积的平均值范围.方法306例18～70岁(平均44岁),男性150例,女性156例,健康志愿者分组后进行头颅MRI扫描,在T1WI上测定颞叶体积.结果男性左侧标准体积均值为97.13mm×7.13mm×7.13mm,95%可信区间为94.64%～99.61%.女性分别为95.12mm×95.12mm×95.12mm,95%可信区间为92.77%～97.47%.男性的右侧标准体积的均值为97.02mm×97.02mm×97.02mm,95%可信区间为94.56%～99.47%.女性右侧标准体积均值为96.42mm×96.42mm×96.42mm,95%可信区间为94.26%～98.59%.经统计检验左侧和右侧颞叶体积分别在性别上无明显差异.结论MRI能提供较为精确的颞叶图像,为临床某些精神和神经系统疾病的诊断和治疗提供有价值的参考依据.

Objective To establish the range of normal value of temporal lobe（TL）volume and its variability in healthy adults with different genders.Methods 306 healthy volunteers,aged from 18～70 years（mean age 44 years）,of both genders（male 150,and female 156）received head MRI scan,after being divided into different groups.And the volume was measured at T1W1.Results Mean value of standard volume of male left TL was 97.13 mm×97.13 mm×97.13 mm,and the 95% confidence interval was 94.64%～99.61%,while they were 95.12 mm×95.12 mm× 95.12 mm and 92.77%～97.47% in female,respectively.The mean value of right side were 97.02 mm×97.02 mm×97.02 mm（male）and 96.4%～22.70%（female）,and the 95% confidence interval were 94.56%～99.47%（male）and 94.26%～98.59%（female）,respectively.After the statistical test,the difference in same side TL volume between male and female wasn＇t significant.Conclusion MRI examination can offer preciser images of temporal lobe,thus valuable and reliable evidence for some mental and neural system diseases in clinical diagnosis and treatment.
