User:Daniel Mietchen/Talks/DigitalSpecimen 2014/Magnetic Resonance Imaging and natural history collections

Abstract
Magnetic Resonance Imaging (MRI) is a digital imaging technique widely used across the life sciences, yet rarely so in the context of natural history collections. This talk will zoom in on this latter subject.

Along with a basic introduction into the methodology underlying MR imaging and MR spectroscopy, an overview will be given about applications to specimens preserved in various ways - e.g. in alcohol or cryobanks or through mummification or fossilization - as well as to living or fresh specimens in the context of comparative investigations with specimens from collections. This will be complemented with examples from MR-based morphometry.

Besides specimen structure, MRI allows to image aspects of specimen dynamics - like ontogenesis, diffusion, hydration or flow - and of chemical composition. This versatility is achieved through a plethora of very specific technical protocols, which poses challenges for data aggregation, preservation and reuse, while providing collections with new avenues for research and for science communication.
