Interslice sensitivity variation in magnetic resonance imaging (MRI) is said to be attributable to crosstalk. Crosstalk is a phenomenon in which deterioration of the rectangular profile of the RF pulse frequency characteristics leads to poor slice profiles, resulting in interference between slices. In the present study, the ideal characteristics of multislice profiles were analyzed through numerical simulation with the Bloch equation using sinc symmetrical RF pulses. The effects of the slice excitation order on the slice profile were also examined, comparing interleaved acquisition and sequential acquisition. The results of the simulation showed that the order of image acquisition affects the slice profile.
