The purpose of this study is to compare the 2D and 3D circumferential strain assessed with MR tagging. 6 healthy volunteers and 5 asymptomatic patients with left bundle-branch block were evaluated. The 2D and 3D timing and peaks of circumferential shortening were compared and the cross correlation was computed. No significant differences between these parameters were observed and high positive correlation coefficients were obtained. This study shows that there is no significant difference between 2D and 3D circumferential strain. Because the 2D strain computation is less time consuming, circumferential shortening should be measured using this approach.
