Magnetization structure contrast based on intermolecular multiple-quantum coherences.

Journal Article (Journal Article)

In vivo and ex vivo MRI based on intermolecular multiple-quantum coherences (iMQC) is predicted to provide a fundamentally different source of contrast for MRI. This article investigates the dependence of image contrast upon the choice of correlation distance for a heterogeneous material. A closely packed array of parallel hollow cylinders was used to demonstrate signal intensity variations when the correlation distance becomes comparable to the gap size between the cylinders. The observed effects agree well with three-dimensional calculations of the time evolution of magnetization under the nonlinear Bloch equations.
