Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest radiographs were obtained . Prominent interstitial markings in the lower lungs , accompanying mild cardiomegaly and small pleural effusions reflect mild pulmonary edema . Patchy opacification obscuring the right heart border could be confluent edema or lung contusion after recent chest compressions . There is no pneumothorax .
    OUTPUT:
    
Mild congestive heart failure . Possible right lung contusion . Although no fracture is seen , conventional chest radiographs are not sensitive for detection of chest cage trauma . Regions where there are focal findings of possible trauma should be clearly marked and imaged with bone detail views .
