Table 2.

Maximum signal leakage (L-) factor for different MB and PESHIFT. Reference maximum L-factor (MB = 3, PESHIFT = 0, dark shaded cell) was based on previous experience (Feinberg et al., 2010). Unacceptable maximum L-factors (> 0.9) are light shaded. ΔS (mm) is the distance between simultaneously excited slices for a given MB factor with whole brain coverage.
