Overall, highresolution connectivity mapping with 7T HYDI offers great potential for understanding unresolved changes in mouse models of brain disease.  ...  Here, we implemented a framework for advanced mathematical analysis of mouse 5-shell HARDI (b=1000, 3000, 4000, 8000, 12000 s/mm 2 ), also known as hybrid diffusion imaging (HYDI).  ...  This method is referred to as multi-shell HARDI, or hybrid diffusion imaging (HYDI).  ...

2015 11th International Symposium on Medical Information Processing and Analysis  
We scanned a healthy mouse brain using 7-Tesla 5-shell HARDI (b=1000, 3000, 4000, 8000, 12000 s/mm 2 ), also known as hybrid diffusion imaging (HYDI).  ...  Diffusion weighted imaging (DWI) can reveal the orientation of the underlying fiber populations in the brain.  ...  We tested out these mathematical reconstruction frameworks -DTI, QBI and GQI, on 5-shell HARDI data (300 diffusion gradients; 60 per shell), also known as hybrid diffusion imaging (HYDI), acquired in a  ...
