Minimal starting time of data reconstruction for qualitative myocardial perfusion rubidium-82 positron emission tomography imaging

Objective Qualitative positron emission tomography (PET) myocardial perfusion imaging (MPI) scans are reconstructed with a delay after an injection of rubidium-82 (82Rb) to ensure blood pool clearance and sufficient left ventricle to myocardium contrast. Our aim was to derive the minimal starting time of data reconstruction (STDR) after an injection of 82Rb for which the diagnostic value and image quality remained unaffected. Materials and methods We retrospectively included 23 patients who underwent rest-stress 82Rb PET MPI using 740 MBq. Patients fulfilling one of the two criteria indicating a slow blood pool clearance (ejection fraction
