Mapping of LM estimates (the quasi-continuous LM ratings (0 to 100)) to simulated BI-RADS assessments. The first mapping (BI-RADS(r5)) is based on the definition given by an experienced MQSA-radiologist in our institution The second mapping (BI-RADS(5)) follows the definition of ACR breast imaging lexicon 2003 for the relation between the LM and the 5-category assessments. The third mapping (BI- RADS(7)) also follows the definition of ACR breast imaging lexicon 2003 with the three additional subcategories for category 4.
