Suggest oblique views of the ribs initially to better localize .
    OUTPUT:
    
No acute cardiopulmonary process seen . A 9 mm opacity projecting over the left sixth rib may be within the bone rather than within the pulmonary parenchyma . Recommend oblique rib views initially to further evaluate .
