Paper Abstract

To date, 696 patients being admitted to the Cardiac Unit have been examined by a new method-Intergated® Radiography-that adds information about cardiovascular pulsations to the conventional admission chest x-ray, without interfering with the ordinary purposes of chest radiography and without increasing radiation dose to the patient. The Intergated Radiography System (IRS) is a simple attachment for existing chest radiography units. It images the heart at end-diastole and end-systole on alternate thin strips of a single film, thus producing a composite image in which moving walls have a serrated appearance that easily permits objective measurement of wall motion while the appearance of stationary thoracic structures is substantially unaffected. Patients with coronary artery disease, aortic regurgitation and left-to-right shunts demonstrate characteristic motion patterns. IRS films compared with ventriculography and aortography show excellent correlation. Preliminary results suggest IRS may increase the diagnostic accuracy of electrocardiographic exercise stress testing for detection of coronary artery disease. Thus Intergated Radiography is a simple and objective method for screening and for following the results of therapy in patients.
