Diffusion weighted imaging (DWI) is increasingly being
used for diagnosing and monitoring treatment response in
breast cancer. The spin-echo EPI sequence commonly used
for DWI is, however, prone to artifacts from B
and fat, leading to distortions and artifacts in breast
imaging. In this work we use a multi-band accelerated
pulse sequence to acquire sagittally, and then reformat
to produce the axial images desired for interpretation.
This approach produces breast diffusion images with
reduced distortion, chemical shift artifacts, and
improved effective resolution in all three dimensions.
