Bland–Altman analysis using visually derived iTPD % demonstrated a mean bias of 6.4; standard deviation of differences: 9.33 and 95% limits of agreement between the two methods: − 12.08 and 24.98. Thus, CT-MPI derived iTPD % overestimated the PET iTPD % by 6.4% on average with the 95% limits as above. The dashed pink line represents the regression line of the differences between CT-MPI and PET iTPD% which shows a positive trend representing that the CT-MPI derived iTPD% overestimation increased with an increasing average of CT-MPI and PET iTPD%.
