Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear unchanged . Central pulmonary arteries appear enlarged . There are persistent widespread multifocal opacities suggesting pneumonia , most extensive in the upper lobes . These are seen in a background diffuse interstitial abnormality which may represent part of a widespread infectious process , although coinciding etiologies such as fluid overload or interstitial lung disease are also possible . A right lower lung opacity which had worsened since the earliest study has now improved slightly , but other opacities are little if at all changed . There is no definite pleural effusion or pneumothorax . The bones appear demineralized . There is a mild anterior wedge compression deformity along the lower thoracic spine , likely chronic .
    OUTPUT:
    
Persistent multifocal opacities suggesting pneumonia , fairly similar in overall distribution ; the only clear change is somewhat improved aeration at the right lung base . A coinciding interstitial abnormality may indicate an additional process such as fluid overload or interstitial disease . Comparison to earlier studies predating acute illness may be helpful to evaluate further and possibly CT if needed clinically .
