Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Suboptimal inspiratory effort and AP position complicates interpretation of the radiograph . Apparent cardiomegaly and prominent pulmonary vascular markings may be technical in nature . Mild elevation of the left hemidiaphragm . Normal diaphragmatic contour . No airspace consolidation . No pleural effusion . No suspicious pulmonary nodules or masses .
    OUTPUT:
    
No airspace consolidation . There is elevation of the left hemidiaphragm , but the diaphragm has maintained its normal contour and I think a subpulmonic effusion is unlikely .
