Representative figures from three patients (left: 3D T1 with CS factor of 2 without DLR [CS2]; right: 3D T1 with CS factor of 4 with DLR [DLR-CS4]). (a) Patient 1: All the metrics were comparable as per the qualitative analysis results, including artifacts diffusely scattered in the white matters and gray-white matter differentiation. (b) Patient 2: The delineation of old infarctions in the corona radiata did not differ significantly between the two sequences. (c) Patient 3: Diffuse, grainy artifacts throughout the white matter were significantly worse in DLR-CS4 compared with CS2; meanwhile the other metrics did not differ significantly
