1  Screening mammography examinations: Mammography examinations indicated by the radiologist to be for screening with bilateral routine views done and no other mammogram within the last 9 months among women without breast implants or a prior mastectomy or a prior breast cancer diagnosis.

2  Sensitivity = The percentage of cancers§ that had a positive initial interpretation&.

3  Specificity = The percentage of non-cancers~ that had a negative initial interpretation#.

4  Recall = The percentage of examinations with a positive initial interpretation&.

5  PPV1 = The percentage of examinations with a positive initial interpretation& that result in a tissue diagnosis of cancer§.

6  PPV2 = The percentage of examinations with a positive final interpretation^ that result in a tissue diagnosis of cancer§.

7  PPV3 = The percentage of examinations with a positive final interpretation^, where it is known that a biopsy was performed as a result of the positive interpretation, that result in a tissue diagnosis of cancer within one year.

§  Cancers = Examinations with a tissue diagnosis of ductal carcinoma insitu or invasive cancer within one year and before the next screening mammography examination.

~  Non-cancers = Examinations without a tissue diagnosis of cancer within one year or before the next screening examination, whichever occurs earlier.

&  Positive initial interpretation = BI-RADS category 0, 4, or 5 (Note: 3 with a recommendation for immediate follow-up was recoded as 0).

#  Negative initial interpretation = BI-RADS category 1, 2, or 3 with no recommendation for immediate follow-up.

^  Positive final interpretation = BI-RADS category 4 or 5 (Note: categories 0 and 3 with a recommendation for biopsy were recoded as category 4).
