Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear unchanged . A convex appearance of the right upper mediastinal contour appears unchanged and was shown to reflect tortuosity of the right innominate artery on the prior CT . Streaky opacities in the lower lungs and plate - like opacification in the lingula appear similar and suggest minor atelectasis or scarring . Streaky posterior opacities on the lateral view appears somewhat more prominent than on the prior radiographs , however , but appear fairly similar to a lateral scout view from a recent prior CT . Accordingly atelectasis is suspected . Moderate degenerative changes are similar along the thoracic spine . Degenerative changes also which effect each shoulder , particularly the right side . The bones appear demineralized .
    OUTPUT:
    
Streaky posterior basilar opacification , somewhat increased but probably compatible with atelectasis ; infection is doubted but hard to completely exclude , however .
