Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a sub - optimal inspiratory effort and low lung volumes . The cardiomediastinal silhouettes are within normal limits . The bilateral hila are unremarkable . Right cardiophrenic angle and diffuse interstitial prominence likely reflects bronchovascular crowding in the setting of low lung volumes . Linear opacities at the left lung base are consistent with subsegmental atelectasis . There is no focal lung consolidation . There is no evidence of pulmonary vascular congestion . There is no pleural effusion or pneumothorax . Degenerative changes of the right glenohumeral joint are noted .
    OUTPUT:
    
No acute cardiopulmonary process .
