    INPUT: Frontal and lateral chest radiographs demonstrate low lung volumes . Port - A - Cath remains in unchanged position . Cardiomediastinal contour is unchanged and again demonstrates minimal cardiomegaly . Calcifications along the tracheobronchial tree and the aortic arch are also noted . Linear opacities at the bases most likely reflect atelectasis . Cephalization of the vessels suggests mild pulmonary vascular engorgement , new from the prior exam . Small bilateral pleural effusions are stable . There is no pneumothorax .
    OUTPUT:
    
1 . Mild pulmonary vascular engorgement and unchanged small bilateral pleural effusions . 2 . Chest radiograph is not sensitive for the detection of pulmonary embolism and Chest CTA is recommended .
