Unless clinical studies demonstrate previously unrecognized changes on serial MR imaging studies under such circumstances which likely are not based on the mechanisms of actions described earlier, the recommendation for short-term follow-up MR imaging after preoperative assessment should be reconsidered

Our results corroborate those of other studies reporting a negative predictive value of more than 99% in masses at US with recognized benign characteristics, which allows greater confidence in the use of the Breast Imaging Reporting and Data System 3 category for US-determined probably benign masses, whether palpable or not, in a manner akin to the established mammographic paradigm
