目的评价应用SPACE(sampling perfection with application optimized contrast using different flip-angle evolution)MR序列行全脑脊液(CSF)体积成像的可行性。方法对12例健康志愿者和26例连续的脑积水病人的脑和脊髓行1.5T SPACE序列检查。根据CSF与背景信号强度的比值差异评估影像的对比度。依据CSF形状的几何学特征和局部解剖学假设对CSF节段进行分割。对志愿者和病人的蛛网膜下腔和脑室的CSF空间体积进行评估,并对其进行线性识别分析。结果 CSF和脑的影像对比度为0.94,CSF和脊髓的影像对比度为0.90。以体模研究为对照,CSF体积测量的准确度为98.5%。应用线性识别分析能够清楚识别病人和健康志愿者。健康志愿者脑室(Vv)和全部蛛网膜下腔的CSF体积(Vs)呈显著的线性回归,Vv=0.083Vs。结论对健康志愿者和脑积水病人行全部CSF体积成像是可行的。可获得CSF体积的整体测量。该方法可用于脑积水病人的诊断与随访。要点①MRI评估CSF体积在健康志愿者/脑积水病人均是可行的。②CSF体积可以整体测量。③健康志愿者蛛网膜下腔与脑室的CSF比值是恒定的。④CSF线性识别分析能够区分病人和健康志愿者。⑤全部CSF体积成像对脑积水的诊断和随访有用。
