Nuclear Magnetic Resonance Technology for Non-Invasive Characterization of Bone Porosity and Pore Size Distributions

Abstract: 

Magnetic resonance technology can be used to non-invasively measure bone porosity, pore size distribution, and other bone properties, including aging, in situ. Spin-lattice (T.sub.1) as well as spin-spin (T.sub.2) relaxation time data and spectra are used to determine porosity and pore size distribution in human bones, including compact bones.
