The author presents a critical analysis of the recently published BI-RADS TM system. The first recommendation is to always determine if BI-RADS TM is being used for mammography, ultrasound or magnetic resonance by using the term BI-RADS TM-US or a similar term. The advantages of using the BI-RADS TM-US including reproducibility, standardization, auditing, basis of echogenicity are also considered. In addition, some drawbacks of the system are identified: the omission of statistically significant proven descriptors such as marked hypoechogenicity and number of lobulations, the use of non-recognized descriptors such as the Cooper ligament, and the lack of data on the positive predictive value of some very common breast lesions such as hypoechoic nodules. Finally, a suggestion is presented: to classify the descriptors according to its importance as predictors in order to determine the positive predictive value of the lesions.
