Imaging of the pulmonary arteries

For decades, classical pulmonary digital subtraction angiography (DSA) has served as the gold standard for the direct assessment of the pulmonary vasculature. During the past decade, substantial advances have been achieved in all cross-sectional imaging modalities in terms of spatial and temporal resolution. As a consequence of that, computed tomography angiography (CTA) and magnetic resonance imaging (MRI) are the modalities of choice for the morphological (CTA) and functional (MRI) assessment and will be presented in the context of the technical developments (CT: from single-slice scanners to modern multi-slic…
