Abstract
MS lesions can be detected by simple subtraction of MRI scans taken before and after the injection of GdDTPA contrast agent. However, this highlights global changes in the post-injection scan in addition to the lesions. We introduce a new non-parametric subtraction measure, analogous to standard statistical tests, which allows a direct probabilistic interpretation of image differences. We demonstrate the technique using scans of MS lesions, but we expect it to be applicable to a wide range of image formation processes.
