Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest . Relatively low inspiratory effort seen on the current exam with secondary crowding of the bronchovascular markings . Linear right basilar opacity is seen most likely due to atelectasis . Superiorly the lungs are clear . The cardiomediastinal silhouette is within normal limits . No acute osseous abnormalities detected .
    OUTPUT:
    
Linear right basilar opacity most likely due to atelectasis given the low lung volumes . Infection is not entirely excluded . If desired , repeat frontal view with improved inspiratory effort can be performed to further clarify .
