These imaging data are examples of sub-millimeter resolution T-weighted EPI (Echo Planar Imaging) acquired using the T23DEPI (T-imaging with 2 3D-EPIs) sequence [1]; functional MRI data with matching resolution and distortion, and MP2RAGE (Magnetization Prepared 2 Rapid Acquisition Gradient Echoes) anatomical images [2], from the same subjects. Data from two protocols and subjects presented in the paper describing the sequence [1] are made available here: 1)0.8 mm protocol: whole brain, axial T23DEPI T-weighted images; a 5-minute fMRI run with the same orientation and 27 mm coverage in the slice selection direction, covering the primary visual cortex. fMRI data were acquired while the volunteer viewed a flashing checkerboard stimulus; the unsmoothed GLM results of the fMRI and a 0.64 mm resolution MP2RAGE from the same subject. These data are from Experiment 3 in [1] 2)0.7 mm protocol: partial brain T23DEPI T-weighted images with longer or shorter readouts; matching coronal echo planar images again acquired while viewing a flashing checkerboard stimulus and a 0.64 mm whole brain MP2RAGE from the same subject. These data are from Experiment 1 in [1].
这些成像数据是使用T23DEPI(具有2个3D-EPI的T成像)序列获取的亚毫米分辨率T加权EPI(回波平面成像)的示例[1];来自同一受试者的具有匹配分辨率和失真的功能MRI数据以及MP2RAGE(磁化准备2快速采集梯度回波)解剖图像[2]。本文描述该序列的论文[1]中呈现的来自两个协议和受试者的数据在此提供:1)0.8毫米协议:全脑轴向T23DEPI T加权图像;一次5分钟的功能磁共振成像扫描,具有相同的方向,在切片选择方向上覆盖27毫米,覆盖初级视觉皮层。在志愿者观看闪烁棋盘格刺激时采集功能磁共振成像数据;同一受试者的功能磁共振成像的未平滑GLM结果和0.64毫米分辨率的MP2RAGE。这些数据来自[1]中的实验3。2)0.7毫米协议:具有较长或较短读出时间的部分脑T23DEPI T加权图像;在观看闪烁棋盘格刺激时再次采集匹配的冠状回波平面图像以及来自同一受试者的0.64毫米全脑MP2RAGE。这些数据来自[1]中的实验1。
