COMMENTS

Findings to be observed in normal lungs include vascular markings composed primarily of the vertically oriented pulmonary artery segments and the horizontally directed pulmonary veins toward the left atrium. The gradual decrease in size of the vessels as they branch peripherally should be noted. Close to the hilar structures the smaller bronchials seen as thin walled darker circles. Edematous thickening of these bronchial walls are one of the earliest findings of congestive failure.
