【摘要】:目的采用磁共振成像(MRI)時(shí)間-空間標(biāo)記反轉(zhuǎn)脈沖序列測(cè)量不同年齡組正常人中腦導(dǎo)水管的腦脊液峰值流速,探討腦脊液的流動(dòng)規(guī)律。方法選取健康志愿者41例,年齡7~73歲;其中男23例,女18例,按不同年齡分為4組:7~15歲組(n=11),15~35歲組(n=10),35~45歲組(n=9),≥45歲組(n=11),應(yīng)用東芝1.5T MRI 8通道頭顱線圈,采用MRI time-SLIP序列標(biāo)記腦脊液,計(jì)算出中腦導(dǎo)水管內(nèi)腦脊液的峰值流速;測(cè)量中腦導(dǎo)水管的內(nèi)徑及長(zhǎng)度。結(jié)果中腦導(dǎo)水管腦脊液峰值流速,15~35歲組與35~45歲組,≥45歲組,與7~15歲組比較差異均有統(tǒng)計(jì)學(xué)意義(P0.05);中腦導(dǎo)水管的內(nèi)徑和長(zhǎng)度在不同年齡組差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論在中腦導(dǎo)水管,腦脊液呈雙向流動(dòng);MRI time-SLIP序列能實(shí)時(shí)定量測(cè)量腦脊液的流速,能顯示腦脊液的湍流。
[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,
