Hello,

I have a question regarding measurements on mri images.

I have saved a number of images as jpg images.  The measurements on these
jpg images do not seem to correspond to measurements on the workstation.  
This did not occur previously when I saved the images as dicom images.  
Could someone explain to me why this might be and if there is a solution?

Specifically, I have previously saved a number of dicom images and then
loaded these onto imagej.  The measurements that I took corresponded well
to the measurements taken on the workstation.
Now, on a different workstation that uses different software (impax) I
have saved images as jpg images because this seems to be the default, and
when I load these images to imagej the measurements do not correspond.

Any help would be much appreciated,
Thanks,
John
