Lung vessels and airways on CT

Inside the lungs, this TotalSegmentator CT segmentation tells arteries from veins and airways from airway walls on a chest CT scan. Studies use it to compare pulmonary vessel volumes, relate vessels and airways to lung function, and follow both between scans. On PET or SPECT, the same outlines read uptake in arteries, veins, and airways, set against a blood-pool reference region.

Find answers to research questions like: How do pulmonary artery and vein volumes differ by age and sex? How does uptake in the lung vessels change between scan dates? How do vessel volumes relate to lung function?
