MRI and multinuclear MR spectroscopy of 3,200-year-old Egyptian mummy brain.

Abstract

Our objective was to present the MR and MR spectroscopy imaging findings of a 3,200-year-old preserved brain from an Egyptian mummy. In this work, the morphology of the intact specimen was examined by MRI at 1.5 T. Chemistry of the intact specimens was studied by proton spectroscopy at 1.5 T and sodium nuclear MR (NMR) spectroscopy at 4.0 T. Biopsies from the temporal lobes were analyzed by proton and phosphorus NMR spectroscopy (14 T) or rehydrated and stained for paleohistologic study. MRI showed a heterogeneous brain with convolutions, gyri, and air pockets. Paleohistology showed a uniform, disorganized cerebral substance with numerous eosinophilic structures and argentophilic granules. Spectroscopic studies identified bound sodium ions in the specimen and phosphate and free fatty acids in extracts. MR techniques are a nondestructive method for the analysis of adipocere observed in a preserved mummy's brain.
