Diffusion Weighted Whole Body Imaging with Background Body Signal Suppression (DWIBS)
01-Jul-2008
Technical Improvement Using Free Breathing, STIR and High Resolution 3D Display
The AppCNR of 8 mm slice thickness images reconstructed from 4 mm slice thickness source images obtained in a free breathing scan of 430 sec were much better than 9 mm slice thickness breath-hold scans obtained in 25 sec. High resolution multi-planar reformat (MPR) and maximum intensity projection (MIP) images could be made from the data set of 4 mm slice thickness images. Fat suppression was much better in the STIR-EPI sequence than SE-EPI with CHESS pulse. The feasibility of DWIBS was showed in clinical scans of 11 patients. Whole body images were successfully obtained with adequate fat suppression.
Conclusion: Three-dimensional DWIBS can be obtained with this technique, which may allow us to screen for malignancies in the whole body.
