Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lungs are relatively hyperinflated . Right middle lobe atelectasis / scarring is seen . There is no definite focal consolidation . No pleural effusion or pneumothorax is seen . Cardiac and mediastinal silhouettes are stable . No pulmonary edema is seen . Projecting between the posterior right seventh and eighth ribs is a subtle 5 mm nodular opacity , not clearly seen on the prior study . Loss of height of several thoracic vertebral bodies , not well assessed on this study , but likely grossly similar to the prior study . No definite displaced rib fracture , although study is limited in the sensitivity of detector such .
    OUTPUT:
    
Subtle 5 mm nodule opacity projecting between the posterior right seventh and eighth ribs , not clearly seen on the prior study in could represent a pulmonary nodule . Recommend follow - up chest CT for further assessment . No definite displaced rib fracture , although study is limited in the sensitivity of detector such . If clinical concern for rib fracture persists , dedicated rib series or chest CT is more sensitive .
