Today the abdominal aortography is carried out by method of translumbar and percutaneous transfemoral retrograde catherer. We have practiced the intravenous angio-cardiography as one of the X-ray examination for the heart. Recently the contrast medium is remarkable developed in safety and ability of contrast, then it is even possible that we inject 50-100cc of quantity of the contrast media into the vein of patient. By the same technique of the intravenous A.C.G, using the contrast media at rate of 2cc per Kg of patient's weight, we could get easily useful Radiographies of a series of the abdominal aorta without defferent arterial hazard, for example, the hematoma, the arterial damage, the hemorrhage and other arterial trouble, with only retative light ill effects of contrast media, for instance, the light nausea. We could study about timing of exposure for the many abdominal aortographes by intravenous method, and get them as follow. 1) The starting Time of exposure (T) intravenous method is expected from the patients pulse rate (P). T≒-0.1P+17.8 (sec) 2) If we use the number of heart pulses as the time unit, we constantly get the starting time of exposure for aortography at 12th pulse after the injection of contrast media to the arm vein. 3) It is always necessary for the case of the abnormal heart that the arm-tongue circulation time is measured with saccarin liquid. Because the A-T circulation time corresponds with the time at peak opaque by contrast media about the chest aorta, then we can know from A-T circulation time that the starting time of of exposure for the abdominal aortography is 2-3 pulses before A-T circulation time. (a time unit is a pulse of heart.)
