Brest diffusion MRI has been typically performed in an
axial slice orientation with large FOV which tends to
show ghosting artifacts from significant B0 field
inhomogeneity. Sagittal slice orientation is limited due
to long scan time. In this paper, we propose a multiple
slice group slice-accelerated sequence for sagittal
bilateral breast diffusion imaging. One slice on each
slice group out of two was acquired and compared to the
standard technique. The proposed method provided nearly
identical image quality with almost half the scan time
as compared to the standard bilateral diffusion imaging,
suggesting a viable tool for breast lesion
characterization within reasonable scan time.
