Yep. In fact in the case of SNOTE implementable corrections, you can scan the SNOTE changes before you implement the note -> a code scan is just a READ REPORT of the source text into an internal table of the program doing the scan. Via SNOTE you can download the source corrections and append / insert them into the internal table of the source they are correcting, and then use the scan patterns to look for statements.
So you can compare unpatched code to patched code and see what the difference is and then view these differences from various perspectives, including SU24 "view" of the differences.
