Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Portable AP upright chest radiograph was obtained . The lung bases are suboptimally assessed due to lordotic positioning . The previously noted opacity in the right lower lobe is difficult to assess . Consider dedicated PA and lateral views to assess further . In addition , left lung base is poorly assessed . The mid and upper lungs appear well aerated . No large effusion or pneumothorax . Heart and mediastinal contours appear stable . Bony structures are intact .
    OUTPUT:
    
Suboptimal evaluation of the lower lungs which in this patient with recent right lower lobe pneumonia renders this exam incomplete . Recommend dedicated PA and lateral views to more clearly the lung bases .
