Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low , accounting for some bronchovascular crowding . Otherwise , no focal opacities are noted . Moderate cardiomegaly is chronic and stable . Again seen is increased opacity of the periphery of the right lung base laterally underlying rib deformities suggestive of prior trauma and underlying scarring which is unchanged . Blunting of the posterior costophrenic angle is compatible with prominent extrapleural fat confirmed by prior CT scan .
    OUTPUT:
    
No evidence of acute cardiopulmonary process . Stable cardiomegaly and right lung base scarring .
