Benchmarks for Abnormal Diagnostic Mammography Interpretations from 2002 - 2006 --- based on BCSC data as of 2009 by Indication for Examination*
You are viewing the 2009 collection of this data. Data from other times are also available:
Numbers are frequencies unless otherwise indicated.
The first non-zero assessment within 90 days was used as the final assessment for analysis.
* Includes examinations for radiologists who interpreted at least 10 cases in a given column; excludes examinations for which the radiologist is unknown.
† The number of radiologists in this column does not equal the sum of radiologists in the other columns. A given radiologist may contribute to each of the preceding columns, but may contribute to this column only once.
‡ Abnormal interpretation rate = the percentage of examinations with an abnormal final interpretation (BI-RADS category 4 or 5 -- categories 0 or 3 with a recommendation for biopsy were recoded as 4).
|| PPV2 = the percentage of examinations with an abnormal final interpretation that result in a tissue diagnosis of cancer within 1 year.
# PPV3 = the percentage of examinations with an abnormal final interpretation, where it is known that a biopsy was performed as a result of the abnormal diagnostic examination, that result in a tissue diagnosis of cancer within 1 year.
