چکیده
Historical Review The use of isotopes in clinical cardiology was introduced by Blumgart, Yens, and Weiss, who used radium C and a cloud chamber to estimate the linear velocity of blood flow in an extensive series of studies starting in 1927.1, 2 Undoubtedly the major stimulus to the adoption of tracer technics came from the introduction of man-made radioisotopes after World War II. During the immediate postwar period several new methods were described. Quimby and Smith3 and Kety4 introduced the use of isotope clearance as a method of measuring the rate of blood flow to tissues. Prinzmetal and his collaborators used a Geiger counter placed over the precordium to follow the circulation of a bolus of radioactive blood through the right and left sides of the heart. They dubbed this procedure "radiocardiography."3 In 1953, WVaser and Hunzinger made the first attempts

متن کاملUse of external counting technics in studies of the circulation.
• A number of new technics involving external detection of radioactivity in the blood stream or in tissues have been proposed as means for determining the rate, volume and pathway of blood flow in the intact subject. By virtue of their dependence on indirect, external measurement of indicator (isotope) activity in the body as opposed to direct measurement, these technics have been categorized a...
