Orthogonal T2 maps of the knee of a volunteer without osteoarthritis lesions, superimposed on top of fat-suppressed T2-weighted source images. a–c Analytic maps based on standard images (AnT2Fit). d–f Dictionary-based maps of the same standard images (DictT2Fit). The T2 values are visibly more homogeneous in the different segments, while the average T2 value increased. g–i Dictionary-based maps of HD-PROST-denoised images (DenDictT2Fit). While the T2 values remain similar, the denoising is also visually apparent. HD-PROST High-dimensionality undersampled patch-based reconstruction
