Clinical studies evaluating breast DWI have shown that
rs-EPI provides an improved diagnostic performance
compared to ss-EPI. However, one disadvantage of rs-EPI
is a longer scan time, which increases with the number
of readout segments. In this study, we demonstrate the
application of simultaneous multi-slice accelerated
rs-EPI using blipped-CAIPIRINHA to DWI of the breast,
providing a substantial reduction in scan time or
increase in slice coverage or resolution compared to
standard rs-EPI, whilst maintaining image quality.
