A Comparison of Hyperelastic Warping of PET Images with Tagged MRI for the Analysis of Cardiac Deformation

Figure 7

The Bland-Altman analysis comparing the warping strain results with those of the tagged MRI analysis. The warping strain predictions underestimated the strain results compared with the tagged MRI strain predictions. Warping showed little bias in the circumferential direction for both hearts with the linear regression analysis (dashed lines) showing relatively flat slopes in the circumferential strain.
