Abstract

Background: By evaluating 47 performed standard mammographies, we found four pathologies including mass, calcification, asymmetric density, and distortion. Positive predictive value (PPV) of each finding was estimated according to local mammographic findings.Methods: In a cross-sectional, descriptive, analytic study, patients who referred to Seyed-al-Shohada Hospital, Isfahan, Iran, during 2010, for standard mammography were included if they agreed to undergo a local compression view as well. Suspicious findings in the standard mammograms were compared with local compression results.Findings: During four months, 693 mammographies were performed. In 63 cases, local compression view was requested. However, only 47 cases accepted to undergo the test. In standard mammography reports, asymmetries (70%) were the most and distortion was the least reported finding. The highest PPV belonged to mass (62%) and the lowest to distortion. As a whole, PPV was 29% for suspicious standard mammographic findings.Conclusion: Decreasing requests for local compression, especially for asymmetries is recommended.
