While this may be due to an unfolded aorta , tortuosity and dilatation of the ascending aorta is not excluded and this could be further evaluated with chest CT with contrast . Mild pulmonary edema is seen . Degenerative changes are seen along the spine including anterior osteophyte .
    OUTPUT:
    
1 . Clear lungs . 2 . Mild prominence of the ascending aorta which may relate to tortuosity ; however , dilatation is not excluded . Findings could be further evaluated with chest CT with contrast .
