Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Moderately well inflated lungs with unchanged diffuse interstitial edema . Previously noted increased lucency at the left costophrenic angle is unchanged , in appearance compared to the prior radiograph obtained earlier on the same day . Given that there is no apical pneumothorax on this upright view - this may represent a summation shadow or a loculated pocket of air rather than free pleural air . Endotracheal tube tip terminates at the level of the clavicles , enteric tube terminates in the stomach and left PICC terminates at the cavoatrial junction as before .
    OUTPUT:
    
1 . Unchanged diffuse interstitial edema . 2 . Previously noted increased lucency at the left costophrenic angle is unchanged , in appearance compared to the prior radiograph obtained earlier on the same day . Given that there is no apical pneumothorax on this upright view - this may represent a summation shadow or a loculated pocket of air rather than free pleural air - either airways has remained unchanged hence less concerning . 3 . Lines and tubes as above .
