Conclusions: COVID-19 patients display striking anomalies in the distribution of blood volume within the pulmonary vascular tree, consistent with increased pulmonary vasculature resistance in the pulmonary vessels below the resolution of CT. These results suggest that while the pathological changes to the pulmonary vasculature implicated in pulmonary vascular disease (PVD), collectively termed "pulmonary vascular remodeling", occur primarily below the resolution of CT scans, those processes do have a measurable effect on larger, more proximal vessels. In this study we assessed the use of novel CT-derived measures of pulmonary blood volume and pulmonary vascular density in patients with COVID-19.	./cache/cord-320447-nq9f1gmu.txt	./txt/cord-320447-nq9f1gmu.txt
