Teaching Points: Provide a pictoral review of the ultrasound lexicon in the BI-RADS 5th Edition, with emphasis on the changes in the lexicon, to promote appropriate use of the lexicon.
Studies have shown that focused teaching about the BI-RADS lexicon leads to improved appropriate use of the lexicon. Ultrasound images demonstrating the lexicon characteristics will be displayed with the corresponding BI-RADS descriptors. Images depicting the new BI-RADS descriptors (e.g. tissue composition, complex cystic and solid echo pattern) will be shown. A quiz will be provided following the instructive slides to reinforce the appropriate use of the BI-RADS lexicon.
