(a) Block diagrams for single-slice DIR TSE and slice-interleaved TSE without DIR. The removal of DIR pulses enable interleaved slice acquisition. The central ADC of the interleaved acquisition is located at the same cardiac phase as ADC in single slice scheme. (b) In traditional DIR BB imaging, 12 short axis slices are acquired sequentially one slice in each scan. While in the slice-interleaved mode, 3 slices with 300% slice distance are grouped into one interleaved acquisition. For example slice# 1,5,9 (marked in red) are acquired in one scan.
