Women at increased risk for breast cancer require annual mammography and MRI. The purpose of this study is to evaluate cancers detected in MRI screening and assess the visibility on prior MRI-examinations. MRI-scans of breast cancers detected in our MRI screening program were re-evaluated and lesions on the diagnostic MRI and prior MRI were scored according to Breast Imaging Reporting and Data (BI-RADS) MR-lexicon. The visibility of the lesions on the prior MRI was rated as visible, minimal sign and invisible. Our results show that almost one third of the breast cancers should have been recalled based on consensus review.
