Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The left PICC line continues to projects over the left brachiocephalic vein . Advancement by 7 - 8 cm would position its tip at the superior cavoatrial junction . Right middle lobe atelectasis is unchanged . Bilateral lower lobe airspace opacities are unchanged . Small bilateral pleural effusions are stable . Left basilar airspace opacification likely due to atelectasis is also stable . Moderate cardiomegaly despite the projection is unchanged .
    OUTPUT:
