It is probably true that a large num-ber of cardiac cases are sent to the roentgen-ologist because the clinician is afraid thathe may be overlooking a syphilitic aortitisor to check up his diagnosis of that condi-tion. The diagnosis of aortitis should bemade with the greatest caution in casesshowing widened shadows of the great ves-sels. Arteriosclerosis, hypertension, chronicmitral disease, a high diaphragm, or an en-larged pulmonary artery may produce wid-ened shadows of the great vessels.
