Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is rotated towards the right and the lung volumes are noted to be low . Streaky bibasilar opacities likely reflect atelectasis . There is no lobar consolidation , pneumothorax , pleural effusion , or overt pulmonary edema identified . A slightly asymmetrically prominent right hilum is likely secondary to patient rotation . Borderline cardiomegaly is stable but there is no real pulmonary vascular engorgement and certainly no edema . Calcifications are noted at the aortic knob .
    OUTPUT:
    
Chronic borderline cardiomegaly . Low lung volumes and bibasilar atelectasis . No lobar consolidation or pleural effusion .
