High resolution NMR images of sixgill shark (Hexanchus griseus) tissue from both horizontal and sagittal orientations are presented. Structures normally radiographically undetectable are visualised here with NMR. Proton density, spin-lattice and spin-spin relaxation time maps as well as various relaxation weighted images show selective enhancement of different tissue types. Quantitative analysis of major anatomical features in the shark head is provided.
