Magnetic Resonance Method And Apparatus For Quantitative Simultaneous Multi-Slice Assessment Of Tissue Displacement, Deformation, And Related Biomarker Parameters

Abstract

Embodiments relate to a magnetic resonance imaging (MRI) technique in which the two-dimensional (2D) Displacement Encoding with Stimulated Echoes (DENSE) imaging technique and the multiband technique are combined to provide a 2D multi-slice quantitative assessment of displacement, deformation, and mechanics indices of tissue. The scan time is equivalent to the short scan time of the conventional single slice 2D imaging while providing spatial volumetric coverage similar to three-dimensional (3D) imaging. The techniques are combined in both the sequence (i.e., data acquisition) and reconstruction sides. Quantification of tissue displacement and motion is achieved through the combination and further evaluation of tissue mechanical properties is provided by calculating different indices based on the displacement and motion values.
