Of the MRI participants, 16 women (2.6%) had breast cancer diagnosed. The supplemental yield of was 14.7 per 1000 (95%CI,3.5-25.9;P=.004).SensitivityforMRIandmammographyplusultrasoundwas 1.00 0.79-1.00); specificity, 0.65 0.61-0.69); and PPV3, 0.19 0.11-0.29). For mammography ultrasound, sensitivity 0.44 0.200.70, P=.004); specificity 0.84 0.81-0.87; P.001); 0.18 0.08to0.34;P=.98).Thenumberofscreensneededtodetect1cancerwas127(95%CI, 99-167)formammography;234(95%CI,173-345)forsupplementalultrasound;and68 39-286) for after negative ultrasound results.
