Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Low lung volumes are present which accentuate the size of the cardiac silhouette which is mildly enlarged . The mediastinal and hilar contours are unremarkable . Ill - defined somewhat nodular opacities are noted within the upper lobes bilaterally , more pronounced on the left , similar to that seen on the prior CT . Known smaller nodules within the lower lobes bilaterally are better assessed on prior CT . Minimal atelectasis is seen at the left lung base . No pleural effusion , focal consolidation or pneumothorax is identified . Multiple clips are noted within the left upper abdomen compatible with prior nephrectomy . No acute osseous abnormalities demonstrated .
    OUTPUT:
    
Ill - defined nodular opacities within the upper lobes , more pronounced on the left , are similar compared to the prior CT , and again may reflect a drug related pneumonitis . No focal consolidation identified . Minimal atelectasis in the left lung base .
