Corresponding axial CT images and colour overlay maps of CALIPER quantitation of pulmonary vessel volume (red), a volumetric measure of pulmonary arteries and veins within the lung, excluding vessels at the lung hilum in three chronic hypersensitivity pneumonitis patients with mild (a + b), moderate (c + d) and severe (e + f) extents of fibrosis. Note there is misclassification of small regions of the reticular pattern in the paravertebral regions (b) and right lower lobe (f) as vessels
