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 (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. METHODS: Simulations and GE‐EPI were performed at (2mm)...
