Gradient‐echo EPI using a high‐degree shim insert coil at 7 T: Implications for BOLD fMRI

摘要

PurposeTo quantitatively assess the effects of high degree and order (1^st–4^th+) relative to 1^st–2^nd degree B 0 shimming at 7 Tesla (T) on gradient‐echo echo planar imaging (GE‐EPI) and blood‐oxygen‐level dependent (BOLD) activation.
