摘要: Aim To compare readers' performance in detecting architectural distortion (AD) compared with other breast cancer types using digital mammography. Materials and methods Forty-one experienced screen readers (20 US 21 Australian) were asked to read a single test set of 30 digitally acquired mammographic cases. Twenty cases had abnormal findings (10 AD, 10 non-AD) normal. Each reader was locate rate any abnormalities. Lesion case-based assessed. For each collection (US; Australian; combined), jackknife free-response receiver operating characteristic (JAFROC), figure merit (FOM), inferred (ROC), area under curve (Az) calculated JAFROC v.4.1 software. Readers' sensitivity, location JAFROC, FOM, ROC, Az scores between groups Wilcoxon's signed ranked statistics. Results lesion-based analysis, significantly lower sensitivity ( p =0.001) shown on AD non-AD for all collections. The analysis demonstrated ROC values =0.02) the first readers, second =0.04) all-readers =0.008), Conclusions current work demonstrates that remains challenging task even era.
