Results are presented over all subjects, cardiac phases, and anatomical segments (n = 150). Mean Diff = mean difference, LoA = limits of agreement – ±1.96. *Standard deviation mean difference.

COV = coefficient of covariance, r = correlation coefficient, P = probability value, ICC = intraclass correlation coefficient.
