The pulmonary vasculature consists of a large arterial and venous tree with a vast alveolar capillary network (ACN) in between. Both conducting blood vessels and the gas-exchanging capillaries are part of important human lung diseases, including bronchopulmonary dysplasia, pulmonary hypertension and chronic obstructive pulmonary disease. Morphological tools to investigate the different parts of the pulmonary vasculature quantitatively and in three dimensions are crucial for a better understanding of the contribution of the blood vessels to the pathophysiology and effects of lung diseases. In recent years, new stereological methods and imaging techniques have expanded the analytical tool box and therefore the conclusive power of morphological analyses of the pulmonary vasculature. Three of these developments are presented and discussed in this review article, namely (1) stereological quantification of the number of capillary loops, (2) serial block-face scanning electron microscopy of the ACN and (3) labeling of branching generations in light microscopic sections based on arterial tree segmentations of micro-computed tomography data sets of whole lungs. The implementation of these approaches in research work requires expertise in lung preparation, multimodal imaging at different scales, an advanced IT infrastructure and expertise in image analysis. However, they are expected to provide important data that cannot be obtained by previously existing methodology.

用于分析肺血管系统的立体学和三维重建

肺血管系统由一棵大动脉和静脉树组成,中间有一个巨大的肺泡毛细血管网络 (ACN)。传导血管和气体交换毛细血管都是重要的人类肺部疾病的一部分,包括支气管肺发育不良、肺动脉高压和慢性阻塞性肺病。定量和三个维度研究肺血管系统不同部分的形态学工具对于更好地了解血管对肺部疾病的病理生理学和影响的贡献至关重要。近年来,新的体视学方法和成像技术扩大了分析工具箱,因此扩大了肺脉管系统形态分析的决定性力量。本文介绍和讨论了其中三个发展,即(1)毛细管环数量的立体量化,(2)ACN的连续块面扫描电子显微镜和(3)在光学显微镜下标记分支代基于全肺微计算机断层扫描数据集的动脉树分割的部分。在研究工作中实施这些方法需要肺准备、不同尺度的多模态成像、先进的 IT 基础设施和图像分析方面的专业知识。但是,它们有望提供以前存在的方法无法获得的重要数据。(2) ACN 的连续块面扫描电子显微镜和 (3) 基于全肺微型计算机断层扫描数据集的动脉树分割的光学显微镜切片中分支代的标记。在研究工作中实施这些方法需要肺准备、不同尺度的多模态成像、先进的 IT 基础设施和图像分析方面的专业知识。但是,它们有望提供以前存在的方法无法获得的重要数据。(2) ACN 的连续块面扫描电子显微镜和 (3) 基于全肺微型计算机断层扫描数据集的动脉树分割的光学显微镜切片中分支代的标记。在研究工作中实施这些方法需要肺准备、不同尺度的多模态成像、先进的 IT 基础设施和图像分析方面的专业知识。但是,它们有望提供以前存在的方法无法获得的重要数据。先进的 IT 基础设施和图像分析方面的专业知识。但是,它们有望提供以前存在的方法无法获得的重要数据。先进的 IT 基础设施和图像分析方面的专业知识。但是,它们有望提供以前存在的方法无法获得的重要数据。
