Before revision:  This study addresses this issue by developing a computational algorithm to determine pulmonary hemodynamics ( blood pressure and flow ) in a large network of arterial vessels and subsequently quantify the uncertainty of these predictionsto geometric variation associated with image segmentation.
After revision:  This study quantifies the variability of one-dimensional (1D) CFD predictions by propagating the uncertainty of network geometry and connectivity to blood pressure and flow ) in a large network of arterial vessels and subsequently quantify the uncertainty of these predictionsto geometric variation associated with image segmentation.
