    INPUT: Rotated positioning . Allowing for this , no definite change is detected . Again seen are patchy opacities at both lung bases , possibly minimally worse at the left lung with base laterally . Allowing for this , no new areas of opacity are identified . Mild vascular plethora appears slightly improved . Possible small pleural effusions , not significantly changed . Right IJ line , tip over distal SVC , again noted . No pneumothorax detected .
    OUTPUT:
    
1 . Slight improvement in vascular plethora . 2 . Possible minimal increased opacity at the lateral edge of the previously seen left base patchy opacity . 3 . Otherwise , I doubt significant interval change . 4 . Right base patchy opacity remains present .
