Constrained reconstruction is making use of additional image information to improve the precision in the reconstruction of undersampled MR data. Here we use co-registered CT-data as an anisotropic diffusion constraint to improve sharpness in short T2* images reconstructed from undersampled 3D UTE data of a mummified human hand. The results are compared to other established reconstruction methods.
