a) Schematic of the alternating acquisition pattern. The T2Prep duration is alternated between 60, 30 and 0 (no T2Prep) ms from heartbeat to heartbeat. All images are acquired in an interleaved fashion and on average experience similar motion. b) Schematic of the conventional sequential acquisition pattern. The T2Prep duration is changed only after acquisition of an image. This approach may be more vulnerable to irregular heart rates or respiration patterns. c) Simulations of stability of fitted T2 values for both methods against heart rate variation. For an input T2 of 45 ms, both the alternating acquisition (solid line) and the sequential acquisition (dashed line) result in a T2 variation of ~3 ms over the range of physiological heart rates.
