FYI--the American College of Radiology created the BI-RADS 
terminology precisely for the purposes of providing a controlled 
lexicon for radiology observations on mammography. Extensions on this 
are needed to describe findings in ultrasound and MRI (future work in 
BI-RADS). There is a possibility that these terms will be 
incorporated into RadLex as well. Thus, you might not want to build 
on this, focusing on adding the clinical indications or other 
information that is not related to image observations.
