Motivation: Radial imaging is desirable for whole body imaging due to its motion robustness. However, two-point Dixon with bipolar readouts can have reduced quality due to gradient errors.
Goal(s): To develop improved imaging capabilities by leveraging gradient impulse response function (GIRF) measurements to correct for gradient errors and yield better image quality.
Approach: A radial two-point Dixon acquisition was compared using GIRF-corrected and uncorrected reconstructions in phantoms and a human volunteer.
Results: The use of GIRF in the reconstruction of two-point Dixon radial imaging provides improved image quality and better fat-water separation and provided similar quality to a Cartesian acquisition.
Impact: This work demonstrates improved image quality and improved fat-water separation by incorporating gradient impulse response function compensation in two-point Dixon radial imaging for an intended application of motion-robust whole body MR imaging.
