3D-EPI QSM has been proposed as one solution of QSM long scan time which hinders its routine application. As its validity has been ascertained in our phantom study, in-vivo reliability study is warranted. This healthy participant study demonstrated excellent reliability of 3D-EPI QSM with 2 minutes’ scan time, compared to the “standard” 5 minutes’ GRE QSM, favoring further study to evaluate its actual clinical performance.
