Hi Guys,

I had encounter a problem when loading the dicom files of DTI obtained from Philips Achieva 3.0T. The file can be read but can not be shown correctly. There are some warnings  
 ![warning](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/0/0/00c1470cf847e838c4f55222b85ddfda20faeca1.png) and the DTI data was not shown correctly.

 ![show](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/0/e/0edfc072ad8fceac1481203d6358fe6d0a20862b.png)  
I also modified the setting according to the warning, but the DTI data was still not shown correctly. Any advice about this problem is appreciate!

Hi @wpgao -

For diffusion MRI, install the SlicerDMRI extension: [http://dmri.slicer.org/](http://dmri.slicer.org/) and try again.

Best,

Hi Steve,

Thanks. It’s done!  
In fact, the module “DWIConvert” could convert the diffusion weighted dicom into nrrd file.
