From: 82Rb PET imaging of myocardial blood flow—have we achieved the 4 “R”s to support routine use?
a Combined estimation (N = 60) of 82Rb extraction function parameters from three validation studies performed in humans using the one-tissue-compartment model, without correction (spillover or scaling) of the arterial blood input function. b Combined estimates of the 82Rb extraction parameters: A (0.79 ± 0.035) and B (0.55 ± 0.11) demonstrate improved precision vs. individual studies (Germino, Prior, Lortie). Confidence interval (CI) values derived from Table 3 in Germino et al. [1]
