Characteristic configurations are often to be seen in the various forms of valvular and congenital heart disease, in syphilitic artistes and in aneurysm of the heart. Congestion and oedema of the lungs and small pleural effusions can be shown radio logically before they can be detected clinically. The individual chambers of the heart and the great vessels may be visualized by the injection of a radio opaque material into a vein or by catheter directly into the heart before taking a series of radiographs in rapid succession. Such studies are very useful in the differentiation of various congenital cardiac lesions and of vascular from other abnormal meditational shadows. The phonocardiorgraph records heart sounds and murmurs and may help to elucidate difficult problems of auscultation.
