Sensitivity and Specificity by Indication for Examination for 714,984 Diagnostic Mammography Examinations from 1996 - 2005
Note: 23,653 (5.2%) examinations were given an initial BI-RADS assessment of zero. The first non-zero assessment within 180 days was used as the final assessment for analysis. Examinations without a non-zero assessment within 180 days were excluded (N=7,943; 1.7%). * Sensitivity = the percentage of cancers that had an abnormal interpretation (BI-RADS category 4 or 5). † True Positive = the number of cancers that had an abnormal interpretation (BI-RADS category 4 or 5). ‡ Cancers = the number of 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). || True Negative = the number of non-cancers that had a negative interpretation (BI-RADS category 1, 2, or 3). # Non-cancers = the number examinations without a tissue diagnosis of cancer within 1 year following the examination.
