Subject: RE: RadLex Thoracic Lexicon meeting Wed 4/23

Obviously Paul put a lot of thought into his comments!  Thank you!

I have just one comment regarding the degree of difficulty.  The 
reason to include such a category has nothing to do with confidence 
in diagnosis, etc., and everything to do with a meaningful retrieval 
after the database gets very large.  When you have hundreds of cases 
of some unusual lung disease, you want some ways to pick out the 
cases of interest for a particular conference or retrospective 
research study.  The degree of difficulty is one way to help 
sub-select cases with the same diagnoses, etc.
