Abstract
OBJECTIVE: The standardized terminology and reporting structure of the BI-RADS for mammography, ultrasound, and MRI findings facilitates patient management. To date, no such terminology has been available for gamma camera breast imaging. We present an illustrated lexicon including description of background uptake, mass and nonmass uptake, lesion intensity, associated findings, and review of common artifacts. CONCLUSION: This proposed lexicon should facilitate standardized interpretation, communication of results, and outcomes monitoring of examinations using dedicated devices for gamma camera breast imaging.
