Diffusion-weighted imaging (DWI) of abdominal organs can
require considerable measurement time, especially if
respiratory triggering is performed. Here we present an
approach to reduce the scan time of abdominal DWI by
multiband-accelerated technique utilizing simultaneous
radiofrequency excitation and acquisition of multiple
slices. Our results reveal that a reduction of measuring
time at least by 50 % is achievable without substantial
compromising image quality using respiratory triggering.
Multiband-accelerated technique seems to be a promising
approach to reduce acquisition time in abdominal DWI
applications for clinical routine.
