This study’s purpose was to compare non-respiratory and respiratory- triggered proton density and T2-weighted DIXON fat suppression sequences for high-resolution brachial plexus MRI. In a cohort of 5 volunteers and 20 patients, we were able to demonstrate that respiratory triggering substantially reduced ghosting artifact and improved delineation of nerve fascicular architecture with acceptable increased scan time.
