The goal of this work was to apply the blipped
CAIPIRINHA slice acceleration technique to spin echo EPI
based whole-body DWI and compare the results with a
conventional non slice accelerated acquisition. 8
healthy volunteers and 6 patients were scanned with both
sequences. Quantitative comparison between the two
sequences showed similar ADC values in multiple organs.
Qualitative comparison showed comparable image quality
and diagnosis in all 6 patients with both sequences.
