Patients entering hospitals in the USA are reported to have about one chance in three of having a radioactive tracer play a role in the diagnosis of their medical problem. , One important diagnostic technique is radionuclide imaging — the use of radioactive isotopes to obtain images of body organs and processes. The IAEA, from its very beginning, has paid close attention to this particular fiel...
Planar equilibrium radionuclide angiography (ERNA) is used to determine global and regional measures of ventricular function (primarily left ventricular [LV] function) at rest and/or during exercise stress or pharmacologic intervention. These measures of ventricular function may include evaluations of ventricular wall motion, ejection fraction (EF), and other parameters of systolic and diastoli...
R-wave-synchronous radionuclide angiography provides time-activity curve information that is assumed to be proportional to ventricular volumes. We performed serial 2-minute time-activity curves and simultaneous Fick cardiac outputs before and during graded, maximal, supine exercise in nine normal subjects; each subject exercised without drug intervention, after nitroglycerin and after intraveno...
