[Mristudio-users] pre-compiled AIR exe files?

Thu May 1 13:35:42 EDT 2008

Hi, 

  I am trying to get the AIR software installed in preparation for the tutorial workshop this weekend, but am having trouble figuring out how to do it on my Vista machine. Is there a way that I can get the precompiled .exe files (makeaheader.exe, alignlinear.exe and align_warp.exe) from someone who has already done it and then just copy them to my own Landmarker directory?

  Thanks for the help!

Dear All,

Is there a way to obtain the radial and axial diffusivity values from a 3D
image in DTIStudio in the same way that FA values can be obtained?

Also, are there any solid review articles you would recommend on the
biological significance of radial and axial diffusivity as measured with
DTI?

Thank you,
Igor

Hi Susumu,

Just to clarify, the room number is TWH FP6-103. That is the Toronto Western
Hospital, Fell Pavilion, 6th floor, room 103 (399 Bathurst Street
Toronto, Ontario, Canada M5T 2S8 )

Hi Igor,

Axial diffusivity is the same as Eigenvalue0 in DtiStudio.

Radial diffusivity is (Eigenvalue1 + Eigenvalue2)/2. DtiStudio doesn't
provide this number. I think we should add this for the next version.

You can create (Eigenvalue1 + Eigenvalue2) image using the calculation
function of RoiEditor, once you saved Eigenvalues.

The advantage of using the axial / radial diffusivity is this;

When you observe "lower FA", there are two possible mechanisms;

1) It's low because the longest axis (Eigenvalue0 or axial diffusivity)
decreased

2) It's low because the second and third (Eigenvalue1 and Eigenvalue2 or
radial diffusivity) increased.

These two possible mechanisms can't be differentiated by FA (information
degeneration), which may carry important biological information. In many
cases, #1 and #2 occur simultaneously, though.

You may want to read the SK (Victor) Song's series of papers on this
subject. I'm not aware of review papers about it.

Susumu

Dear MriStudio Users who are planning to attend the tutorial in Toronto,

Thank you for your attendance to the tutorial that will be held in Toronto
this Sunday. I also want to send special thanks to Dr. Karen Davis who will
host this session. This will be a free and casual session. To maximize the
efficiency of the tutorial, please read the following instructions very
carefully.

1) We will not provide any computers. Please bring your own laptops. 

2) Please go to www.mristudio.org -> Workshop and follow the instructions.
This will precondition your laptop.

3) Please download all the software (DtiStudio, Landmarker, RoiEditor) and
sample data in the "Workshop". A new sample data ("ProcessedData) were added
recently. Even if you have already download them, please make sure to visit
there once more and make sure you already have all the posted data,
especially "ProcessedData".

Please let us know if you have any questions.

Sincerely,

Susumu Mori
