BI-RADS v2025: Mammo, US, MRI, CEM Updates Harmonized

BI-RADS v2025 brings mammographic density alignment with Mammography Quality Standards Act, nonmass lesions on ultrasound, revised MRI enhancing lesion terminology, and first dedicated contrast-enhanced mammography section, harmonizing lexicon across modalities.

• Mammography: breast density terms now align with MQSA, DBT guidance expanded, and the standalone 'developing asymmetry' descriptor removed.
• Ultrasound: nonmass lesions, elasticity descriptors, and automated breast US terminology now included; MRI enhancing lesion terminology revised and implant descriptors expanded.
• Contrast-enhanced mammography (CEM) gains its own modality section, with lexicon and reporting harmonized across all modalities.
