Top: Radial tagging on a stationary uniform phantom in a double oblique imaging plane(Left) and a healthy volunteer at diastole and systole (Middle and Right). The tortional motion of the LV is well pronounced at the posterior wall. Bottom: circular tagging on a phantom (Left), its K-Space representation (Middle), and on a healthy volunteer (Right). The effect of circular tagging is well separated in K-Space.
