### Image Analysis  
Image examples are shown in Figures 1 and 2. A detailed overview of the scores is provided in Table 2 and Figure 3.  
Overall inter-readout agreement across all sequences and metrics was almost perfect, with alpha = 0.933. On a per-sequence basis, inter-readout agreement was also substantial and ranged from alpha = 0.883 (CS 1 sequence) to alpha = 0.959 (CS 1-SRR-s sequence). As for the scores of subjective image quality metrics, there were significant differences between the sequences. In terms of overall image quality, the CS 3 sequence was deemed significantly worse (\(p<0.004\)), while the CS 1-SRR-s sequence was deemed significantly better (\(p<0.04\)) than the CS 1 sequence. The CS 3-SRR-s sequence was rated comparable to the CS 1 sequence (\(p>0.6\)). In terms of the presence of artifacts, the CS 1-SRR-s, CS 3, and CS 3-SRR-s sequences all performed worse than did the CS 1 sequence (\(p<0.003\)). For delineation of GWM in the temporal gyri, the CS 3 sequence performed worse than the CS 1 sequence (\(p<0.001\)), while the CS 1-SRR-s and CS 3-SRR-s sequences performed comparably well (\(p>0.06\)). Figure 1: Coronal CS 1, CS 1-SRR-S, CS 3, and CS 3-SRR-s images of the hippocampus. Red arrowheads point to the internal hippocampal architecture (HIA) on the left side, and green arrowheads point to the normal HIA on the right side, specifically pointing at the linear dark band of white matter of the stratum radiatum, lacunosum, and moleculare (SRLM) that separates the outer hyperintense gray matter of the subiculum and CA1 to CA3 sectors from the inner hyperintense gray matter of the CA4 sector and dentate gyrus. This anatomical morphology results in a spiral appearance in the coronal plane due to the adjacent layers of gray and white matter. For the visibility of the fornix, the CS 3 sequence performed worse than the CS 1 sequence (\(p<0.001\)) while the CS 1-SRR-s and CS 3-SRR-s sequences performed comparably well (\(p>0.1\)). For the delineation of the hippocampal internal architecture on the left side, the CS 3 sequence performed worse (\(p<0.004\)), while the CS 1-SRR-s sequence performed better (\(p<0.005\)) than the CS 1 sequence. The CS 3-SRR-s sequence was rated comparable to the CS 1 sequence (\(p>0.3\)). Figure 2: Coronal CS 1, CS 1-SRR-S, CS 3, and CS 3-SRR-s images of the hippocampus. Red arrowheads point to the internal hippocampal architecture (HIA) on the left side, and green arrowheads point to the normal HIA on the right side, specifically pointing at the linear dark band of white matter of the stratum radiatum, lacunosum, and moleculare (SRLM) that separates the outer hyperintense gray matter of the subiculum and CA1 to CA3 sectors from the inner hyperintense gray matter of the CA4 sector and dentate gyrus. This anatomical morphology results in a spiral appearance in the coronal plane due to the adjacent layers of gray and white matter. Blue arrowheads point to the fornix (columna fornix) on the left and right side; orange arrowheads point to the mammillary bodies on the left and right side; yellow arrowheads point to the pes hippocampi on the left and right side. Concerning the visualization of the mammillary bodies, the CS 3 sequence was rated worse than the CS 1 sequence (\(p<0.01\)), while the CS 1-SRR-s and CS 3-SRR-s sequences were deemed comparable (\(p>0.3\)). As for the visualization of the pes hippocampi on the left side, the CS 3 sequence was rated worse than the CS 1 sequence (\(p<0.01\)), while the CS 1-SRR-s and CS 3-SRR-s sequences were deemed comparable (\(p>0.1\)). As for the visualization of the pes hippocampi on the right side, the CS 3 sequence was rated worse than the CS 1 sequence (\(p<0.02\)), while the CS 1-SRR-s and CS 3-SRR-s sequences were deemed significantly better (\(p=0.02\)). Concerning the visibility of the CA3/4 dentate gyrus on the left side, the CS 3 sequence was rated worse than the CS 1 sequence (\(p\leq 0.008\)), while the CS 1-SRR-s and CS 3-SRR-s sequences were deemed comparable (\(p>0.2\)).
