Accurate Pulmonary Artery and Vein Segmentation from Non-Contrast CT Scans Reveals Demographic Associations in Pulmonary Vasculature Anatomy

Accurate and abundant segmentation of pulmonary arteries and veins can be achieved from non-contrast CT scans using the proposed HiPaS framework, enabling contrast-agent-free diagnosis and revealing novel associations between pulmonary vessel abundance and sex and age.
