Abstract
Attempt were made to detect the existence of myocardial ischemia by means of both radiographic and scintigraphic techniques. Firstly, a new polygraph was especially designed for selecting the arbitrary phases in a cardiac cycle at which the corresponding radiogram should be synchronously obtained. A comparative investigation on the difference between end-systolic and-diastolic cardiac transverse diameters revealed a remarkable difference of 3.6% in normal subjects and 0.6% in patients with ischemic heart disease. These data indicating the difference of overall heart size was reflected in local dyskinesis documentation of recently developed techniques. For daily clinical purposes, radiography of the chest based on synchronously selected phases would contribute to accurate diagnosis and treatment of heart disease. Secondly, scintigraphic display using intravenously injected thallium-201 was clinically applied. For detection of ischemia, comparative study was performed of initial image relative to selective coronary cineangiography and stress scintigraphy. The former indicated a good correlation of 90%, whereas the latter served to enhance sensitivity. Sequential images (initial and delayed) facilitated the distinction of normal, necrotic, and ischemic areas. Scintigram was used for objective evaluation of coronary dilator (dilazep), either at immediate or follow-up stage. In the same way, it was also possible to indicate the effectiveness
