Movement-related artefacts (MR-ART) dataset

Here we present MR-ART (Movement-Related ARTefacts), a dataset of T1-weighted 3D structural MRI images of heads of 148 healthy adults covering the adult lifespan. Images have been acquired while staying still and while slight and more excessive head motion (i.e. three sets of data for each participant). The 3D structural images are anonymized and organized according to the Brain Imaging Data Structure (BIDS). Facial information was removed using PyDeface. We also include the MRIQC report for each scan to provide general image quality metrics, which allows for more granular labelling. Finally, we provide artefact scores obtained from trained neuroradiologists for each scan to characterize the impact of the movement artefacts on the clinical use of the images.

本文介绍MR-ART（Movement-Related ARTefacts，运动相关伪影）数据集。该数据集包含148名覆盖成人全生命周期的健康成年人的头部T1加权三维结构磁共振成像（T1-weighted 3D structural MRI）图像。所有图像分别采集于受试者保持静止、轻度头部运动以及过度头部运动三种状态下，即每位受试者对应三组数据。该三维结构图像已完成匿名化处理，并按照脑成像数据结构（Brain Imaging Data Structure，BIDS）进行组织。已使用PyDeface工具去除图像中的面部信息。本数据集还包含每幅扫描图像的MRIQC报告，以提供通用图像质量评估指标，支持更精细化的标注。最后，本数据集提供由受训神经放射科医师为每幅扫描图像评定的伪影评分，用于表征运动伪影对图像临床应用的影响。
