Take a closer look at the sharpness between img 1 and img 2. The slice position is almost the same, sorry for that. However, it shows clearly what image is the sharpest. TR and scantime almost the same. BW, TE, FOV, inter echo spacing, ETL, ipat, interpolation, slice thickness etc. the same. One important parameter determining sharpness of the images would be?#s_mri #mri#siemens
