Benchmarks for Sensitivity and Specificity for 2,264,089 Screening Mammography Examinations from 2002 - 2006 --- based on BCSC data as of 2009
You are viewing the 2009 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 row as designated; excludes examinations for which the radiologist is unknown.
** Sensitivity = the percentage of cancers that had an abnormal initial interpretation (BI-RADS category 4, 5, 0 -- category 3 with a recommendation for immediate follow-up was recoded as 0).
† True Positive = the number of cancers that had an abnormal initial 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 initial interpretation (BI-RADS category 1, 2, or 3 with no recommendation for immediate follow-up).
|| True Negative = the number of non-cancers that had a negative initial interpretation.
# Non-cancers = the number of examinations without a tissue diagnosis of cancer within 1 year following the examination.
