Abstract :Aim: To audit our mammography screening practice according to the American College of Radiology insert ignore into journalissuearticles values(ACR); recommendations in the years 2017 and 2018. Method: We documented and analyzed our breast imaging data collected between March 14th, 2017 and December 31st, 2018 and performed a medical audit related to our mammography screening practice. The results were evaluated according to ACR BI-RADS recommendations and performance benchmarks. Results: The total number of mammographic screening patients who had no personal history of breast cancer was 2413 in 2017 and 2018. Our PPV1, PPV2 and PPV3 values were 5.6%, 30.8%, 52.9% accordingly. The recall rate was 11%. Outcomes for cancer detection rate, minimal cancer rate, early-stage cancer rate and lymph node negativity were 0.74%, 50%, 77% and 64% respectively. Conclusion: The mammographic screening outcomes are in accordance with ACR performance benchmarks. Despite a desired high early cancer detection rate, axillary lymph node negativity was found to be below the desired range of 75%. Medical auditing is important for a breast imaging unit to monitor the effectiveness of screening and diagnostic procedures and presents as an effective feedback tool to improve the practice.
