This paper presents a fully automated method to segment the complex left atrial (LA) cavity, from 3D Gadolinium-enhanced magnetic resonance imaging (GE-MRI) scans. The proposed method consists of four steps: (1) preprocessing to convert the original GE-MRI to a probability map, (2) atlas selection to match the atlases to the target image, (3) multi-atlas registration and fusion, and (4) level-set refinement. The method was evaluated on the datasets provided by the MICCAI 2018 STACOM Challenge with 100 dataset for training. Compared to manual annotation, the proposed method achieved an average Dice overlap index of 0.88.

Spatial Registration Evaluation of [18F]-MK6240 PET
图像配准是神经影像学中的一个重要的预处理步骤,它允许模态和受试者之间的解剖和功能信息的匹配。如果图像几何形状或信号强度存在明显差异,则这可能具有挑战性,例如在某些分子PET放射性配体的情况下,对照受试者显示颅内区域内相对于噪声相对缺乏信号,并且可能具有可能与其他区域混淆的脱靶结合,并且可能因受试者而异。在这种情况下,使用中间图像或体积已被证明有助于配准。为了解释我们自己的纵向老化队列中的这种现象,我们从广泛分布的30名淀粉样蛋白阴性受试者中生成了人群特异性MRI和PET模板。然后,我们使用三组不同的配准参数和程序,将这些受试者中的每一个的PET图像,以及三十个“模板初始”受试者的保留集与其相应的MRI图像配准,其中使用模板图像作为中间体。为了评估传统配准和我们的方法的性能,我们将其与作为参考的衰减CT(在PET采集时采集)与MRI的配准进行了比较。然后,我们使用我们的模板直接推导SUVR值,而不使用MRI。我们发现,传统的注册是一个现有的CT为基础的标准相媲美,并有没有显着差异的错误,集体之间的所有方法进行测试。此外,现有和无MR tau PET定量方法之间没有显著差异。我们的结论是,基于模板的方法是一种可行的替代方案,或挽救,直接注册和MR少量化;和,可能是首选的情况下,有疑问的两种图像模式之间的相似性。
