Figure 3 Representation of myocardial deformation using magnetic resonance tissue tagging. An example of a short-axis image with deformed tagging grid on end systole is shown (A). Tagging is achieved by the application of spatial modulation of magnetization (SPAMM) (18). The tag-tag distance is 7 mm. Using the SPAMMVU software package, the intersection points of the tagging grid can be marked (B) and tracked throughout the cardiac cycle (C). The displacement of these points can be measured, and subsequently the intramural myocardial deformation can be quantified.
