NIMH NHGRI data-sharing project

An MRI dataset of 441 individuals from 321 nuclear families, containing a T1w anatomical scan for each subject. At the time of the scan are individuals did not have any psychiatric disorders, as assessed by clinician-administered interviews.
High resolution (1.07 x 1.07 x 1.2mm) T1 weighted volumetric structural imaging data were collected on a 3-T GE Signa scanner with an eight-channel head coil. Magnetization prepared rapid gradient echo (MPRAGE) sequences were obtained with ASSET preparation (124 slices, 1.2mm slice thickness, 224 x 224 acquisition metric, flip angle = 6°, field of view = 24 cm2).
The anatomic images were visually inspected by two raters and given scores of 1 (good quality); 2(moderate motion or other artifacts); 3(severe motion or other artifacts); 4 (unprocessable)

本磁共振成像（MRI）数据集包含来自321个核心家庭的441名个体，每位受试者均拥有一份T1加权（T1w）解剖扫描图像。经临床医生实施的访谈评估证实，所有个体在扫描时均未患有任何精神疾病。
高分辨率（1.07×1.07×1.2mm）T1加权容积结构成像数据采用3-T GE Signa扫描仪及八通道头线圈采集。采用带ASSET准备的磁化准备快速梯度回波（MPRAGE）序列获取图像，具体参数如下：124层，层厚1.2mm，采集矩阵224×224，翻转角6°，视野24 cm²。
解剖图像由两位评级者进行视觉检查，并根据质量赋予1至4分：1（质量良好）、2（中度运动或其他伪影）、3（重度运动或其他伪影）、4（无法处理）
