T2 maps of the knee cartilage with a cartilage lesion. a, b The maps are superimposed on top of fat-suppressed T2-weighted images that were used to compute the maps. c The lower standard deviation of the denoised map reveals an inhomogeneity in the T2 values of the anterior lateral cartilage (white arrow), which was confirmed by a radiologist to be a lesion after reading clinical routine images. The sharp edges of the inhomogeneity also illustrate that the denoising retained the sharpness of the map
