Before revision:  This is particularly important in the case of pulmonary hypertension , as the pulmonary circulation transports oxygen to the lungs via a rapidly bifurcating network of highly compliant blood vessels. However, medical image analysis is subject to uncertainty, which can lead to variation in fluid model predictions .
After revision:  This is particularly important in the case of pulmonary hypertension (PH), which requires a combination of invasive and non-invasive procedures for diagnosis. Uncertainty in image segmentation can easily propagate to CFD model predictions, making uncertainty quantification crucial for subject-specific models .
