To determine the appropriate 82Rb administration dose for two-dimensional dynamic image acquisition, one volunteer had a low and a standard dose of 82Rb (480 MBq and 1600 MBq). The low dose (480 MBq) was based on previous three-dimensional 82Rb dynamic studies [4, 15, 18]. The standard dose, 1600 Mbq, was based on the American Society of Nuclear Cardiology guidelines for relative perfusion imaging . The quality of left ventricular myocardium input function was evaluated in both studies.
