    INPUT: The PICC line is present . The tip is not well delineated , but appears overlies the distal SVC , unchanged . No pneumothorax is detected . There are low inspiratory volumes , with rotated positioning . Allowing for this , again seen is cardiomegaly with a left ventricular configuration and opacification of the left lobe , which likely represents combination of left lower lobe collapse and / or consolidation and a small amount of left pleural fluid . Again seen is patchy opacity at the right base and a a small right pleural effusion though these findings are also improved compared with ___ . Mild vascular plethora is probably also slightly improved . The undulating appearance along the lower right chest is unchanged , but raises question of old rib fractures . Incidental note is made of a plate and screws overlying the cervical spine .
    OUTPUT:
    
Left lower lobe opacification is unchanged . Slight interval improvement in vascular plethora , right base patchy opacity , and small right effusion .
