Wall thickness and diastolic motion influence myocardial T2. A young female volunteer has an apical septal wall thickness of 2 mm (A). In m-mode projections (B) and (E) the y-axis indicates distance in mm, the x-axis indicates time within the cardiac cycle in ms. The red bar represents the acquisition window. In this case M-mode projection reveals residual diastolic motion of 2.8 mm (B). Apical septal T2 was 80 ms (C). A 46-year-old male volunteer of had an apical-septal wall thickness of 7 mm (D), a diastolic wall motion of 1.3 mm (E) and a segmental T2 of 55 ms (F).
