Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are slightly reduced but are improved compared to ___ radiograph . Coarse reticular opacities are present with a peripheral and basilar predominance in keeping with known history of chronic interstitial lung disease . On the lateral view , a subtle area of opacity has developed overlying the lower thoracic spine . It is uncertain whether this represents a confluent area of fibrosis or an early focus of pneumonia . Otherwise , there are no new areas of opacity compared to the prior chest radiograph . No pleural effusions are evident . Cardiomediastinal contours are within normal limits and without change .
    OUTPUT:
    
1 . Chronic peripheral and basilar interstitial lung disease , which may be due to fibrotic NSIP or UIP . 2 . Subtle opacity overlying the lower thoracic spine on the lateral radiograph , possibly due to a coalescing area of basilar fibrosis . However , if the patient is experiencing infectious symptoms , an early focus of pneumonia should be considered , and follow up radiographs may be helpful in this regard . This information has been entered into the radiology communications dashboard on ___ .
