The radiographic appearance of the pulmonary vasculature in the cat.
The purpose of this study was to determine the dimensions of the pulmonary arteries and veins in the cat, both in normal animals and those with evidence of intrathoracic disease. The radiographs of 50 normal cats, 35 cats with hypertrophic cardiomyopathy (HCM), and 15 cats with other intrathoracic disease were assessed. The normal range for the right cranial lobar artery compared with the proximal third of the fourth rib was 0.5-1.0, with a mean artery-to-rib ratio of 0.70 (standard deviation +/- 0.13). Normal cats had a mean vein diameter of (0.20 +/- 0.03 cm) (P = 0.034) compared with cats with HCM, which had a significantly greater mean vein diameter (0.22 +/- 0.04 cm).
