MR images of a child mummy were acquired on a clinical 3T system using a dedicated RF coil with optimized RF switching hardware and 3D UTE sequence. In addition, dual-energy CT images were sampled and co-registered to compare MRI signal intensities and T2* relaxation times with CT Hounsfield Units and effective atomic numbers in bone, soft tissue and embalming material.
