Keywords: Neurography, MSK
Motivation: In 3-D double-echo steady-state sequence with water excitation, fat suppression may be incomplete due to system imperfections, such as B0 and B1 inhomogeneity.
Goal(s): This study describes implementing an adapted Dixon reconstruction to further suppress residual fat signal.
Approach: The images between default and proposed reconstructions were compared in 16 patients undergoing routine upper extremity MR neurography.
Results: The preliminary results demonstrated the feasibility of using the proposed reconstruction to remove residual fat signals incompletely suppressed by the water excitation.
Impact: A benefit of the further suppressed fat provided by the proposed reconstruction was the improved depiction of small, yet clinically important peripheral nerves (particularly subcutaneous sensory branches surrounded by fat).
