a VD projection. Caudal lobar vein (depicted by orange solid line) and veins at where they intersect with the 9th rib (depicted by green solid line) were considered enlarged if they were more than 1:1 ratio. This cat had bilateral enlarged caudal pulmonary veins and arteries with a scant volume of pleural effusion. b Lateral projection. Cranial lobar veins (depicted by orange solid line) were considered enlarged if it was more than 0.7 times the proximal third of the 4th rib (depicted by green solid line). This cat had enlarged cranial lobar veins and arteries, severely enlarged globoid cardiac silhouette with a scant volume of pleural effusion
