引言本研究的目的是确定轴位和冠状位磁共振成像（MRI）在检测高凸度和高中线区域脑脊液（CSF）间隙狭窄方面的性能，方法回顾性研究10例特发性正常压力脑积水（iNPH）患者的横断面和冠状面T1- 14名iNPH患者和12名年龄匹配的对照的加权图像。狭窄的CSF空间在高凸度/中线盲目评价5个评级使用连续的置信度等级的受试者工作特征（ROC）analysis.Results轴向和冠状面成像准确地确定了狭窄的脑池/沟的存在下，在高凸度/中线，并能够预测可能/明确的iNPH具有很高的准确度。结论MRI轴位和冠状位T1 WI均能准确显示高凸度/中线处狭窄的CSF间隙，有助于临床医生对iNPH患者治疗策略的选择。
Introduction The aim of this study was to determine the performance of axial and coronal magnetic resonance imaging (MRI) in detecting the narrowing of the cerebrospinal fluid (CSF) space at the high convexity and high midline areas, which is speculated to be one of the clinical characteristics of idiopathic normal pressure hydrocephalus (iNPH).Methods We retrospectively examined axial and coronal T1-weighted images of 14 iNPH patients and 12 age-atched controls. The narrowness of the CSF space at the high convexity/midline was blindly evaluated by five raters using a continuous confidence rating scale for receiver operating characteristic (ROC) analysis.Results Axial and coronal imaging accurately determined the presence of the narrow cisterns/sulci at the high convexity/midline and was capable of predicting probable/definite iNPH with a high degree of accuracy. there were also no significant differences in the detection of this finding between the axial and coronal images.Conclusion Both axial and coronal T1-weighted MRI can detect the narrow CSF space at the high convexity/midline accurately and may therefore facilitate clinicians in choosing a management strategy for iNPH patients.
