Benchmarks for Sensitivity and Specificity for 4,032,556 Screening Mammography Examinations from 1996 - 2005 --- based on BCSC data as of 2007
You are viewing the 2007 collection of this data. Data from other times are also available:
Numbers are frequencies unless otherwise 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 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 without a recommendation for immediate work-up)
|| True Negative = the number of non-cancers that had a negative interpretation
# Non-cancers = the number of examinations without a tissue diagnosis of cancer within 1 year following the examination
