FIGURE 5. (A) Correlation of LVEF obtained from GBP PET (C¹⁵O) and pFAST (¹³NH₃ PET) in all subjects (n = 40). LVEF values from GBP and pFAST correlate well, although there was slight underestimation of LVEF with pFAST, and stronger tendency for underestimation was observed in patients with defect () compared with patients without defect (•). Dashed line is line of identity. (B) Bland-Altman plot also shows underestimation of LVEF by pFAST compared with GBP by -4.58% ± 7.49%. Lines indicate mean and mean ± 2 SD.
