Experimental Verification of Rubidium-82 for Measuring Myocardial Perfusion
(A) Initial validation of absolute myocardial perfusion using rubidium-82 measured by epicardial radiation detectors compared with microspheres. Reproduced, with permission, from Goldstein et al. (33). (B) Validation of CFR measured by PET imaging of rubidium-82 using the “simple flow model” compared with the more complex complete compartmental modeling, both having comparable correlation with CFR measured by flow meter. Reproduced, with permission, from Yoshida et al. (25). Abbreviations as in Figure 1.
