Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac silhouette is enlarged but stable in size . Enlargement of central pulmonary vessels is consistent with previously provided history of pulmonary arterial hypertension . On the frontal view , there are no focal areas of consolidation . However , diffuse increased density is present overlying the spine on the lateral view , which is limited by combination of low lung volumes and respiratory motion . Minimal basilar interstitial opacities may reflect interstitial edema and have improved since previous ___ radiograph of ___ . Small bilateral pleural effusions are present as well as a small amount of fluid in the fissures . High - grade compression deformity in the mid thoracic spine is unchanged since ___ .
    OUTPUT:
    
1 . Cardiomegaly and minimal interstitial edema . 2 . No definite pneumonia , but basilar pneumonia can not be fully excluded on lateral radiograph . Considering the suboptimal technique on the lateral view , repeat lateral radiograph with improved inspiratory level may be helpful to exclude basilar pneumonia if warranted clinically .
