Simultaneous R2* Relaxometry and Dixon Imaging of Liver and Kidney at 3T Using Bilateral Orthogonality Generative Acquisitions Method

Motivation: Improving the quality of body R2*( T2* ) images by removing transmit field inhomogeneity while utilizing Dixon imaging in body at 3T. Goal(s): Implementation of Bilateral Orthogonality Generative Acquisitions method for simultaneously obtaining homogeneous R2*( T2* ) and Dixon imaging fro kidney and liver at 3T. Approach: Bilateral Orthogonality Generative Acquisitions method was improved to include phase effect that enables the use of Dixon Imaging. Multi-echo acquisitions are utilized for R2* estimation. Results: Implementation of Bilateral Orthogonality Generative Acquisitions method enables the simulataneous R2*( T2* ) and Dixon imaging and eliminates the central brightnening effect. Impact: Simultaneous homogeneous R2*( T2* ) and Dixon imaging is implemented within same scan time required for Dixon imaging while removing the central brightening effect in body imaging at 3T.
