CMR tagging using the SPAMM (spatial modulation of magnetization) technique in a healthy volunteer in axial plane. (a, b, c) and enlarged view at end systole (d). The tags are oriented in long-axis direction, and positioned on the heart at end diastole. Because of shear motion between visceral and parietal layer, the continuity of the tags gets lost during cardiac contraction (arrows)(d).
