CLINICAL APPLICATION OF READOUT-SEGMENTED (RS)-EPI FOR DWI IN PEDIATRIC BRAIN

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 读出分段（RS）-EPI已被建议作为EPI的替代方法，用于高分辨率弥散加权成像。 DWI（弥散加权成像），减少失真。在此，使用3 T扫描仪采集了35名儿科患者的RS-EPI和EPI图像。 全身系统和8通道头部线圈。我们儿科常规使用的ASSET加速EPI序列 医院进行比较。一名儿科神经放射科医生对DW图像进行了评估，并根据 分辨率、失真水平、SNR、病变显著性和诊断置信度。 要了解卢卡斯中心正在进行的其他项目，请访问http://rsl.stanford.edu/ （卢卡斯年度报告和 ISMRM 2011摘要）

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Readout-segmented (RS)-EPI has been suggested as an alternative approach to EPI for high resolution diffusion-weighted imaging (DWI) with reduced distortions. Here, RS-EPI and EPI images were acquired on 35 pediatric patients using a 3T whole-body system and an 8-channel head coil. An ASSET-accelerated EPI sequence used routinely at our pediatric hospital was acquired for comparison. A pediatric neuroradiologist evaluated the DW images, scoring them in terms of resolution, distortion level, SNR, lesion conspicuity, and diagnostic confidence.
