Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is mildly enlarged with a left ventricular configuration . The mediastinal and hilar contours appear unchanged . Patchy medial right basilar opacity obscuring the right cardiophrenic sulcus suggests minor atelectasis . Blunting of the left costophrenic sulcus persists but is less striking than before . Lungs appear hyperinflated . There is no definite pleural effusion or pneumothorax although a very small persistent left - sided effusion is hard to exclude . Two calcified left lung nodules appear unchanged . Streaky left mid lung opacities suggesting minor scarring are likewise unchanged .
    OUTPUT:
    
No evidence of acute process .
