Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low , which results in bronchovascular crowding . Positioning of the patient is somewhat suboptimal . Increased interstitial markings and indistinctness of the hila is consistent with mild interstitial pulmonary edema . Cardiac silhouette appears grossly unchanged . A large hiatus hernia noted . No pneumothorax or consolidation . Wedge compression fractures of T8 and T9 , unchanged compared to the prior radiographs from ___ . ___ deformity at L1 , unchanged compared to a prior lumbar spine radiograph from ___ . Compression fracture at L3 , unchanged compared to the prior chest radiograph from ___ .
    OUTPUT:
    
Mild interstitial pulmonary edema , although this may be exaggerated by low lung volumes . Multiple compression deformities in the thoracic and lumbar spine appear unchanged compared to prior studies .
