This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. This is part of a multi-center traveling subject reproducibility study of DTI. The data will be used to evaluate the reliability of a diffusion tensor imaging protocol that will be used as part of a PREDICT, which is a multi-center (multi-vendor) DT imaging study of Huntington's disease (HD). The DTI data will be used to evaluate reliability of scalar metrics as well as fiber tracking of the motor, oculomotor, and limbic circuits. The 5 subjects will be recruited at Iowa and sent with an oil phantom to a number of centers where they will be imaged using a protocol that includes T1, T2, and Diffusion weighted images (see attached PDF). The scans will occur on Friday, October 19th, from 2pm-8pm. The images collected at our site as well as the images from the other sites will be transferred to Iowa for evaluation.

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 这是DTI多中心旅行受试者重复性研究的一部分。这些数据将被用来评估扩散张量成像协议的可靠性，该协议将被用作预测的一部分，这是一项针对亨廷顿病(HD)的多中心(多供应商)DT成像研究。DTI数据将用于评估标量指标的可靠性以及电机、眼动仪和边缘电路的光纤跟踪。这5名受试者将在爱荷华州被招募，并与石油模型一起被送到多个中心，在那里他们将使用包括T1、T2和扩散加权图像的协议进行成像(见附件PDF)。扫描将于10月19日星期五下午2点至8点进行在我们网站收集的图像以及从其他网站收集的图像将被转移到爱荷华州进行评估。
