Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Nodular opacity in the left mid lung is perhaps slightly smaller compared to the prior study although the opacities were substantially better compared to the ___ chest radiograph which could reflect areas of prior hemorrhage into the nodules or superimposed infection which is now improving . Lung volumes are slightly improved with persistent elevation of the right hemidiaphragm . Right basilar atelectasis is more dense than prior . Left basilar atelectasis is improved . Mild cardiomegaly is stable . No pleural effusion or pneumothorax .
    OUTPUT:
    
1 . Persistent elevation of the right hemidiaphragm with increased atelectasis at the right lung base . 2 . Nodular opacities in the left mid lung are perhaps slightly smaller than prior ; although , substantially larger than the ___ chest radiograph . These changes in size could reflect hemorrhage into the nodule or superimposed infection which is now improving
