Z-score generation
Normative pediatric z-score generation was performed on the 523 LV 3D
datasets. The optimum exponents are shown in Table 2 as well as the mean
and SD of indexed parameters. Figure 1 demonstrates the normative data
and z-score for ESV, EDV, and SV. As can be seen the EDV, ESV and SV
volumes did not have a linear relationship with BSA, but rather a slight
concave curvilinear relationship.
