【摘要】：目的:于磁共振正中矢状位成像测量正常婴儿颅腔面积,并归纳正常值范围,探讨其与月龄的相关性及性别差异。方法:从临沂市人民医院图片存档与通信系统(picture archiving and communication system,PACS)中选取2012年—2015年期间行MRI检查的符合入组标准的婴儿共741例,其中男性446例,女性295例,按不同月龄段分为12组。于磁共振正中矢状位T1flair像上测量幕上面积、幕下面积、全颅面积,计算幕上/幕下面积比值,对所测得的数据进行统计分析。结果:(1)正常婴儿,幕上面积、全颅面积、幕下面积随着月龄的增加而增大,与月龄呈明显正相关、线性回归关系。(2)幕上/幕下比值一月龄组最大,五月龄组最小,五月龄组以后比值再次逐渐增大。(3)四月龄组至八月龄组期间,幕上面积、幕下面积的增长速度相对缓慢。结论:正常婴儿颅腔正中矢状位磁共振成像颅腔面积各测量值参考值范围具有一定的变化规律,可以作为临床评价颅腔发育的指标之一。
[Abstract]:Objective: to measure the area of cranial cavity in normal infants with magnetic resonance median sagittal imaging (MRM), and to conclude the normal range of values, and to explore the correlation and gender difference between MRI and age. Methods: from the picture archiving and communication system of Linyi people's Hospital, 741 infants were selected for MRI examination from 2012 to 2015, including 446 males and 295 females, who were divided into 12 groups according to the age of different months. The supratentorial area, subtentorial area and total cranial area were measured on T1flair images of median sagittal position. The ratio of supratentorial area to subtentorial area was calculated and the measured data were statistically analyzed. Results (1) in normal infants, the supratentorial area, total cranial area and subtentorial area increased with the increase of age, and were positively correlated with the age, and the linear regression relationship was .2.The ratio of supratentorial / subtentorial ratio was the largest in the one-month group, and the smallest in the 5-month-old group. After 5 months of age, the ratio gradually increased again. (3) the growth rate of supratentorial area and subtentorial area was relatively slow during the period from 4 months to 8 months old group. Conclusion: the reference range of cranial cavity area in normal infants with median sagittal magnetic resonance imaging has a certain variation rule, and it can be used as one of the indexes to evaluate the development of cranial cavity.
