†BI-RADS®: BI-RADS® category, an integrated BI-RADS category assessment based on conventional imaging (mammography and/or ultrasound), according to higher concern in any of or the two combined imaging modalities.
-
‡There were 17 lesions from 17 patients having outside mammography and/or ultrasound and the detailed statements of BI-RADS® categories were not obtained, and thus leaving 281 lesions for evaluation.
- BI-RADS® Category 3: probably benign finding.
- BI-RADS® Category 4A: a lesion with low suspicion level for malignancy.
- BI-RADS® Category 4B: a lesion with intermediate concern for malignancy.
- BI-RADS® Category 4C: a lesion with moderate concern for malignancy.
- BI-RADS® Category 5: a lesion which is highly suggestive of malignancy.
- B: benign (including high-risk lesions); M: malignant.
- Cut-off (1): the cut-off value of 0.30; cut-off (2): the cut-off value of -0.72.
- ln(OD)>= the selected cut-off value indicated IR-test positive, and < the cut-off value indicated IR-test negative; ln(OD): ln(odds).
- Sen: sensitivity = (true-positive number)/(the number of malignant disease status); while true- positive indicated IR-test positive as well as disease positive (malignant).
- Spe: specificity = (true-negative number)/(the number of benign disease status); while true-negative indicated IR-test negative as well as disease negative (benign or high risk lesions).
