Mammo MQSA Flashcards
What is the definition of a positive mammography screening examination?
BIRADS 0
What is the definition of a positive diagnostic mammography examination?
BIRADS 4 or 5
What is the definition of a negative diagnostic mammography examination?
BIRADS 1, 2 or 3
What is the definition of a false negative mammography examination?
A cancer that is diagnosed within 1 year of a screening exam that was assigned BI-RADS® 1 or 2 (negative screening exam) or a cancer diagnosed within 1 year of a diagnostic exam assigned BI-RADS® 1, 2 or 3 (negative diagnostic).
What is the different between PPV1, PPV2 and PPV3?
PPV1: The percentage of all positive SCREENING examinations that resulted in a diagnosis of cancer within 1 year of the screening exam.
PPV2: The percentage of all positive DIAGNOSTIC examinations recommended for tissue diagnosis or surgical consultation that resulted in a cancer diagnosis within 1 year of the diagnostic exam.
PPV3: The percentage of all BIOPSIES performed as a result of a positive diagnostic examination that resulted in a cancer diagnosis within 1 year of the biopsy. aka positive biopsy rate
What is the ACR BI-RADS® Atlas definition of cancer detection rate? And what is the acceptable rate?
the number of cancers detected per 1000 patients examined
Acceptable cancer detection rate: greater than or equal to 2.5 cancers per 1,000 examinations
What is the ACR BI-RADS® Atlas definition of the abnormal interpretation rate? What is the acceptable rate?
The percentage of exams interpreted as positive.
For screening mammography, the abnormal interpretation rate is the same as the recall rate. Acceptable abnormal interpretation (recall) rate: 5%-12% of screening exams
Are BI-RADS® 3 assessments included for consideration when determining an abnormal interpretation rate for a diagnostic exam?
No. A positive diagnostic exam are exams that were given BI-RADS® 4 or 5 assessments. A BIRADS® 3 assessment is considered a negative exam for a diagnostic study.
Are BIRADS 6 cases included in the audit?
No.
What is the definition of a minimal cancer?
A minimal cancer is an invasive cancer that is less than or equal to 1 cm in size, or DCIS of any size. Note that even if the size and/or extent of DCIS is extensive, this is still considered a minimal cancer.
According to the ACR BI-RADS® Atlas what are the 3 major goals of breast cancer screening?
Paraphrased: 1) high cancer detection rate in a screening population 2) do this with an acceptable recall rate and biopsy rate 3) find a high percentage of curable cancers (small, node negative)
What breast cancer information is calculated by the audit?
Percentages of node-negative, minimal and stage 0 and stage 1 cancers (to calculate % of cancers detected that are curable)
How often is the breast imaging audit performed?
An audit must be initiated no later than 12 months after the date a new facility becomes certified and then completed within an additional 12 months of when the audit was initiated. The audit should then be completed every 12 months thereafter.
What entity oversees the MQSA?
the FDA. MQSA passed in 1992.
How many months of mammography is required during residency?
3 months
