[Mristudio-users] dwi images in analyze

[Lisa Marie Langevin]

If our images load in a different direction than we expect, how do we fix it?

In  our case, the top right image has anterior toward the bottom of the screen, instead of anterior oriented toward the top of the screen.

When you first time load the Analyze data, or when you reload it as the raw (REC) file, please go over the pull-down menu in the "image tab" to inspect all loaded images. Check these;

>How many images are there?
>Where is the b0 image?
>Do they look correct images?
>The brain positions are all the same?
>what are the image dimensions and how many slices in each data?

Then when you load the REC file for tensor calculation and specified the gradient table, check the image dimension, the number of slices, the total number of gradient orientations, and position of b0 (0, 0, 0).

They should all match.

When you got that message, one of these parameters are wrong.

Hi guys,

When I do this, I get an error message saying the file size is smaller than the DW-image size.

What am I doing wrong?

load the images using "File->MriView 3D", re-save them as "RAW" format, and then
use "File->DTI Mapping" for the re-saved file as "Philips REC" format.
