Over 6 years, 184 women underwent 477 screening MRIs. There were 44 lesions recalled for second-look ultrasound in 39 women. Twenty-seven lesions had a core biopsy, from which 10 malignant lesions were identified. Nine of these were invasive ductal carcinoma, of which all were either grade 2 or 3, varying in size from 4 to 34 mm. One case of ductal carcinoma in situ was identified. The remaining 17 lesions were benign. Women who had a normal ultrasound either had an interval MRI after 6 months or were returned to routine yearly screen.
