Multiband (MB) technique is combined with multitasking for increased spatial
coverage of the heart without prolonging scan time. Two different MB multitasking implementations were developed and compared with the conventional multitasking
technique.

simultaneously in MB multitasking, while separately in single-slice
multitasking.
