1. It is importannt to recognize "Ultrasound non-mass lesions (U-NML)” on breast ultrasound (US), which will become essential with increase in use of automated breast ultrasound (ABUS) imaging. 2. To detect and count suspicious features of U-NML helps interpreters assess possibility of malignancy.  

Breast US is reported to detect incremental cancers that are negative on mammography, especially in women with dense breasts. ABUS enables radiologists to evaluate the breast comprehensively using three-dimensional sectional views, in a similar way to MRI. With a rising number of ABUS exams, it will become increasingly important to appreciate US lesions that would be observed as non-mass enhancements on MRI. Radiologists will be able to appreciate and evaluate “U-NML” properly after viewing this exhibit containing following topics; 1. U-NML in comparison with mammographic and MRI findings, as well as pathology results: what kind of lesions can appear as non-mass? 2. Categorization of U-NML based on scores of suspicious features.
