Parkinson׳s disease (PD) is a neurodegenerative disease that primarily affects the motor functions of the patients. Research and surgical treatment of PD (e.g., deep brain stimulation) often require human brain atlases for structural identification or as references for anatomical normalization. However, two pitfalls exist for many current atlases used for PD. First, most atlases do not represent the disease-specific anatomy as they are based on healthy young subjects. Second, subcortical structures, such as the subthalamic nucleus (STN) used in deep brain stimulation procedures, are often not well visualized. The dataset described in this is a population-averaged atlas that was made with 3 T MRI scans of 25 PD patients, and contains 5 image contrasts: T1w (FLASH & MPRAGE), T2w, T1-T2 fusion, phase, and an R2* map. While the T1w, T2w, and T1-T2 fusion templates provide excellent anatomical details for both cortical and sub-cortical structures, the phase and R2* map contain bio-chemical features. Probabilistic tissue maps of whiter matter, grey matter, and cerebrospinal fluid are provided for the atlas. We also manually segmented eight subcortical structures: caudate nucleus, putamen, globus pallidus internus and externus (GPi & GPe), thalamus, STN, substantia nigra (SN), and the red nucleus (RN). Lastly, a co-registered histology-derived digitized atlas containing 123 anatomical structures is included. The dataset is made freely available at the MNI data repository accessible through the link http://nist.mni.mcgill.ca/?p=1209.
帕金森病(PD)是一种主要影响患者运动功能的神经退行性疾病。PD的研究和外科治疗(如深部脑刺激)通常需要人脑图谱来进行结构识别或作为解剖学标准化的参考。然而,目前用于PD的许多图谱存在两个缺陷。首先,大多数图谱并非基于患病个体,而是基于健康的年轻受试者,因此无法体现疾病特异性解剖结构。其次,深部脑刺激手术中使用的一些皮质下结构,如丘脑底核(STN),在这些图谱中往往显示不佳。本文描述的数据集是一个群体平均图谱,由25名PD患者的3T MRI扫描数据制成,包含5种图像对比:T1加权像(快速小角度激发和磁化准备快速梯度回波)、T2加权像、T1 - T2融合像、相位像和R2图。虽然T1加权像、T2加权像和T1 - T2融合模板为皮质和皮质下结构提供了出色的解剖细节,但相位像和R2图包含生物化学特征。该图谱还提供了白质、灰质和脑脊液的概率性组织图。我们还手动分割了8个皮质下结构:尾状核、壳核、苍白球内侧部和外侧部(GPi和GPe)、丘脑、STN、黑质(SN)和红核(RN)。最后,还包括一个共同配准的源自组织学的数字化图谱,其中包含123个解剖结构。该数据集可通过链接http://nist.mni.mcgill.ca/?p = 1209在MNI数据存储库中免费获取。
