Image quality analysis. Metrics such as SNR as well as no-reference algorithms including BRISQUE and NIQE were used to evaluate the quality of the generated images (3 T*) and compare them with the quality of the original scans (1.5 T and 3 T). The metrics were computed independently on the MRI scans from each study cohort (ADNI-test (ac), NACC (df), AIBL (gi)). Lower value of the metrics indicates improved quality. The symbol “*” indicates p < 0.001 and “**” indicates p < 0.0001
