ABSTRACT:
A method for depicting the anatomy and quantitative tissue strain of a biological tissue. A spatially resolved, double quantum filtered, nuclear magnetic resonance frequency spectrum is acquired from either .sup.1 H or .sup.2 H nuclei in the tissue. Values in the time domain or frequency domain representations of the free induction decay signal are mapped in 2 spatial dimensions so as to selectively depict histological layers of the tissue anatomy. The residual quadrupolar or dipolar splitting is calculated from the free induction decay signal, and then correlated with a tissue strain value by utilizing a known formula describing the correlation between residual quadrupolar or dipolar splitting and tissue strain. The tissue strain value is then mapped in two spatial dimensions.
