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

Purpose To quantitatively assess the effects of high degree and order (1st–4th+) relative to 1st–2nd degree B0 shimming at 7 Tesla (T) on gradient‐echo echo planar imaging (GE‐EPI) and blood‐oxygen‐level dependent (BOLD) activation. Methods Simulations and GE‐EPI were performed at (2mm)3 and (3mm)3...
