DWIBS sometimes suffers from sever
image distortion due to the presence of air within and/or at edge of the FOV.
We demonstrated that whole body DWIBS applied both image based B0 shimming and
blip-up blip-down distortion correction to provide higher robustness.
Figure 2. The MIP of direct
coronal whole body DWIBS at 3.0T were shown. Image based B0 shimming provided
improving depiction of axillary lymph nodes (red circle). Blip-up blip down
distortion correction also decrease distortion effect due to the presence of
air (blue circle).
Figure 4. The MIP of transverse DWIBS at 1.5T were shown. Similar findings
to 3.0T were obtained at 1.5T.
