The Tabar 5-tier grading system is used to classify mammographic lesions. This should not be confused with the Tabar classification of parenchymal patterns in breast imaging. It is a separate but translatable system to the BI-RADS classification system (please note that Tabar grade 3 ≠ BI-RADS 3).
Classification
- grade 1: normal
- grade 2: benign
- grade 3: equivocal/indeterminate
- grade 4: suspicious for malignancy
- grade 5: mammographically malignant
