Great job!  Let me offer a few comments since I will not be able to 
make the meeting.

As for the categories, they are very inclusive and well explained. 
One additional axis that I think may be useful is the type of 
example.  Is the case typical of the diagnosis or unusual?  This 
concept is slightly different than the level of the radiologist 
performing the interpretation.  And it relates to the other axis 
which would be useful - the differential diagnosis.  If the findings 
are well stipulated, perhaps one could build differential diagnoses, 
but it would be easier to list them, I believe.  I am interested in 
hearing your thoughts on this.

Another question regarding categories - are they all compulsory?  Do 
you envision that they will be populated by the committee or 
developed at a later date?

I noticed in the anatomy spreadsheet that some terms (Main bronchus) 
did not have a match in either the ULMS or ACR.  Did you select these 
from SNOMED or just think of them yourself?  And what about SNOMED - 
can we use it?  Do you want to?

Thanks again and I hope you have a productive meeting!
