The Ca shows a significant correlation with age in the DL-QSM-AF3 images ( r = 0.284, p = 0.029) and a marginally significant positive correlation with age in the DL-QSM-AF4 ( r = 0.224, p = 0.088) and DL-QSM-AF5 images ( r = 0.247, p = 0.060). 4 Discussion This study showed that DL-QSM images with acceleration factors of 3, 4, and 5 had good similarity to PI-QSM images, with high correlation in the measured susceptibility values of nuclei ( r > 0.95).
