Numbers are frequencies unless othewise indicated. ** Includes examinations for radiologists with minimum numbers of cases in a given column as designated; excludes examinations for which the radiologist is unknown. * Sensitivity = the percentage of cancers that had an abnormal interpretation (BI-RADS category 0,4,5 or 3 with recommendation for immediate work-up) † True Positive = the number of cancers that had an abnormal interpretation ‡ Cancers = the number examinations with a tissue diagnosis of cancer within 1 year following the examination § Specificity = the percentage of non-cancers that had a negative interpretation (BI-RADS category 1, 2, or 3 without a recommendation for immediate work-up) || True Negative = the number of non-cancers that had a negative interpretation # Non-cancers = the number examinations without a tissue diagnosis of cancer within 1 year following the examination The following source must be cited when reproducing this table: NCI-funded Breast Cancer Surveillance Consortium co-operative agreement (U01CA63740, U01CA86076, U01CA86082, U01CA63736, U01CA70013, U01CA69976, U01CA63731, U01CA70040).
