Discrepant screening mammography assessments at blinded and non-blinded double reading: impact of arbitration by a third reader on screening outcome

Objectives To determine the value of adding a third reader for arbitration of discrepant screening mammography assessments. Methods We included a consecutive series of 84,927 digital screening mammograms, double read in a blinded or non-blinded fashion. Arbitration was retrospectively performed by a...

Description
Summary:Objectives To determine the value of adding a third reader for arbitration of discrepant screening mammography assessments. Methods We included a consecutive series of 84,927 digital screening mammograms, double read in a blinded or non-blinded fashion. Arbitration was retrospectively performed by a third screening radiologist. Two years’ follow-up was performed. Results Discrepant readings comprised 57.2 % (830/1452) and 29.1 % (346/1188) of recalls at blinded and non-blinded double readings, respectively. At blinded double reading, arbitration would have decreased recall rate (3.4 to 2.2 %, p
