Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are hyperinflated consistent with emphysema seen on prior CT . Multiple right - sided pulmonary nodules are again seen , but better assessed on prior CT . Subtle ground - glass opacities in the right lung identified on prior CT likely represent an element of fibrosis . Vascular congestion is difficult to exclude however there is no overt edema . . Mild cardiomegaly stable . Stable calcification of the aortic arch . Blunting of the right costophrenic angle appears chronic and likely represent scarring . Surgical clips projecting inferior to the aortic bulb and along the left neck .
    OUTPUT:
    
1 . Interval improvement of mild pulmonary vascular congestion without overt edema . 2 . Stable pulmonary nodules and solid ground - glass opacities of the right lung seen on prior CT . 3 . Stable emphysema .
