Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Slightly rotated positioning . ET tube tip approximately 6 .4 cm above the carina , at the level of the inferior edge of the mid medial clavicular heads . NG tube present -- likely extends beneath the diaphragm , but is not well visualized , due to underpenetration and cough of film at this level . Note made of probe overlying the lower left chest --___ may lie outside the the patient . No pneumothorax detected . Cardiomediastinal silhouette is unchanged . There diffusely increased interstitial markings , in keeping with findings on the previous film . The asymmetric increased opacity previously seen in right upper and and adjoining midzone appears less dense on the current examination . However , on the current film , there is focal increased hazy opacity in the right mid and lower zones , with new obscuration of the right hemidiaphragm , which may reflect a pleural effusion . The left costophrenic sulcus is grossly clear .
    OUTPUT:
    
1 . ET and NG tube , as described . 2 . Diffusely increased interstitial markings again seen . The right upper zone appears slightly more aerated , though remains diffusely abnormal . 3 . New hazy opacity at right lung base obscuring the right hemidiaphragm . This could reflect a pleural effusion with underlying collapse and / or consolidation .
