Magnetic Resonance Imaging Screening of Women at High Risk for Breast Cancer

This is a clinical practice guideline for women at very high risk for breast cancer. The guideline examines the effectiveness of screening using magnetic resonance imaging (MRI) in these patients, in addition to standard screening (mammography). Optimal frequency of MRI screening, subgroups that may benefit more from MRI screening, and associated harms are discussed. Workup and follow-up are also considered for those patients who have abnormal findings seen only on MRI imaging.
