【摘要】：目的采用磁共振成像(MRI)时间-空间标记反转脉冲序列测量不同年龄组正常人中脑导水管的脑脊液峰值流速,探讨脑脊液的流动规律。方法选取健康志愿者41例,年龄7~73岁;其中男23例,女18例,按不同年龄分为4组:7~15岁组(n=11),15~35岁组(n=10),35~45岁组(n=9),≥45岁组(n=11),应用东芝1.5T MRI 8通道头颅线圈,采用MRI time-SLIP序列标记脑脊液,计算出中脑导水管内脑脊液的峰值流速;测量中脑导水管的内径及长度。结果中脑导水管脑脊液峰值流速,15~35岁组与35~45岁组,≥45岁组,与7~15岁组比较差异均有统计学意义(P0.05);中脑导水管的内径和长度在不同年龄组差异无统计学意义(P0.05)。结论在中脑导水管,脑脊液呈双向流动;MRI time-SLIP序列能实时定量测量脑脊液的流速,能显示脑脊液的湍流。
[Abstract]:Objective to measure the peak velocity of cerebrospinal fluid (CSF) in the aqueduct of normal subjects in different age groups by using the time-space labeled reverse pulse sequence of magnetic resonance imaging (MRI), and to investigate the flow pattern of cerebrospinal fluid (CSF). Methods Forty one healthy volunteers, aged 773 years, including 23 males and 18 females, were divided into 4 groups according to their different ages. They were divided into 4 groups according to their age: 1: 715 years old group, 35 years old group, 45 years old group, and 鈮，
