Dear Amit,
so I guess the explanation that the DICOM tract files cannot be displayed in the software tools you mentioned is that these tools do not support this feature. The DICOM supplement 181 is relatively new, which is probably why this is the case. So there is no issue on the MITK side. Regarding your point 2, this supports the assumption that the format is not supported. Radiant tries to open the DICOM tracts as a DICOM image because it does not support tracts. Sorry that I cannot be of more help, but it looks like you will have to wait for Brainlab to implement supplement 181. I think we have the same issue here in our neurosurgery department. Maybe you can contact Brainlab directly and they might be able to help. Let me know if there is any way I can help, e.g. if it turns out that Brainlab does support the format after all and there simply is a bug in our implementation or theirs.

Radiant doesn't display any images, with pop up - No DISOM images found. 3. I'm unaware whether brainlab neuronavigation software supports the tractography supplement 181 of the DICOM standard. 4.

I require a bit of information to assess the situation properly: 1. Which version of MITK Diffusion are you using? 2. Is there an error message or any other information when you try to import the DICOM fibers in another software? 3. Are you sure that the software you are using actually supports the tractography supplement 181 of the DICOM standard? As far as I know, radiant does not support it for example. Not sure about the others. 4. Could you send me a sample dataset for error analysis?

I exported the .trk tracts as Dicom files using MITK Diffusion, but our neurosurgeons were unable to visualise the tracts in brainlab Neuronavigation software. Our neurosurgeons wanted to import the tracks on brainlab for validation with DES. Even I couldn't visualise the Dicom tracts on Dicom viewers other than MITK diffusion, eg Horos, Radiant. Please advice. Thank you. Best Regards, Amitkumar J. Choudhari, Asst. Prof., Dept of Radiodiagnosis, Tata Memorial Hospital.
