Table 3.

Average ± SD TTP velocity values for R2 and R3 in the basal, mid and apical slices showing no statistically significant differences between the two acquisitions. HighRes values are also shown together with any statistically significant p values for comparisons with R2 and R3. A p value of < 0.05 is considered significant.
