Abnormal Interpretations by Indication for Examination for 714,984 Diagnostic Mammography Examinations from 1996 - 2005
Notes: Numbers are frequencies unless otherwise indicated. 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%). * Abnormal interpretation rate = the percentage of examinations interpreted as suspicious or highly suggestive of malignancy (BI-RADS category 4 or 5). † PPV1 = the percentage of examinations with an abnormal interpretation that results in a tissue diagnosis of cancer within 1 year. ‡ PPV2 = the percentage of examinations with an abnormal interpretation and a recommendation for biopsy or surgical consultation that results in a tissue diagnosis of cancer within 1 year. § PPV3 = the percentage of known biopsies performed as a result of an abnormal interpretation with a recommendation for biopsy or surgical consultation that results in a tissue diagnosis of cancer within 1 year.
