In July 2024, 81 patients underwent brain MRI (DWI, T2, FLAIR, T2*) using a 3-tesla MRI with SR-DLR were prospectively studied.

For each sequence, C-R images were compared with images created from C-R images by SR-DLR (spatial resolution: double or three times, denoising level: level 1 Weak, level 2, level 3 Medium, level 4, level 5 Strong). Imaging conditions are shown in Figure 2. Two radiographers evaluated the overall image quality, noise, sharpness, contrast, and artifacts of each image on a 5-point Likert scale (5 being the best). The scores were compared using the Wilcoxon signed rank test. The scan times of C-R and SR-DLR were compared.
