Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . The frontal view is somewhat underpenetrated , likely due to body habitus . However , given this , no focal consolidation , pleural effusion , or evidence of pneumothorax is seen . The cardiac and mediastinal silhouettes are unremarkable . No overt pulmonary edema is seen . Projecting over the right lateral neck , there is a thin linear radiopaque density measuring 4 .5 cm in length , which is likely external to the patient . If this is a catheter / line , it does not extend into the hemithorax .
    OUTPUT:
    
No acute cardiopulmonary process .
