Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP , lateral , and oblique radiographs of the chest are somewhat limited in the determination of the exact termination point of the right PICC , which is difficult to visualize amongst the mediastinal structures . However , it appears to terminate in the lower portion of the SVC . There has been marked improvement in the bilateral effusions and heterogeneous opacities when compared to the prior study . Prominent interstitial lung markings reflect the patient 's baseline pulmonary fibrosis . There is no pneumothorax . The aorta is stably tortuous with atherosclerotic calcifications in the arch .
    OUTPUT:
    
1 . New right PICC is difficult to visualize but likely ends within the lower SVC . 2 . Marked interval improvement in what was likely multifocal pneumonia as well as near complete clearance of the bilateral pleural effusions compared to ___ . 3 . Stable interstitial lung markings consistent with chronic pulmonary fibrosis .
