Figure 2

Aortic Root dimensions measured manually and semi-automatedly are shown in this figure (table) along with the respective Pearson's correlation coefficients (r) and p values for both ToF (A) and MFS patients (B). Manual measurements were lower than the semi-automated measurements. A significant improvement in Inter-Observer Variability is seen in semi-automated quantification. This effect is more felt on the cusp-cusp measurements. This can be attributed to the greater consistency seen between observers in tracing easily identifiable landmarks. (Obs - Observer; * - p < 0.001 for paired student's T-test between manual and semi-automated measurements.)
