As can be seen comparing these images with their counterparts from Fig. 7, regular reconstructions with parallel imaging but without UNFOLD would not have been a viable option. Parallel-imaging acceleration factors of 3.5 (without partial-Fourier) or 4.5 (with partial-Fourier) were beyond the abilities of our product phased-array coil. Differences between vdSENSE results and SPACERIP results are mostly due to regularization. Notice that when including UNFOLD, and as shown in Fig. 7, good-quality results were obtained instead.
