Key result
Myocardial tagging MRI characterizes normal LV wall motion, revealing concentric contraction and complex systolic rotation.
Why the study?
Normal left ventricular wall motion characteristics using myocardial tagging have not been fully described.
Can MR imaging with two-dimensional myocardial tagging accurately characterize normal left ventricular wall motion in healthy volunteers?
Population
14 volunteers for short axis views and 11 volunteers for 4-chamber view
Design

Can MR imaging with two-dimensional myocardial tagging accurately characterize normal left ventricular wall motion in healthy volunteers?
MR imaging with myocardial tagging is a feasible and detailed method for assessing normal left ventricular wall motion and complex myocardial twisting.
Qi et al. (1993) conducted an observational in Healthy volunteers. Two-Dimensional Myocardial Tagging (MR imaging) was evaluated on Left ventricular wall motion characteristics. MR imaging with myocardial tagging successfully characterized normal left ventricular wall motion, demonstrating concentric contraction, base-to-apex motion, and complex systolic rotation.
