MR-directed ultrasound of MRI-detected lesions was useful for decision making as part of the diagnostic workup. Malignant lesions were likely to have an ultrasound correlate, especially when they presented as masses on MRI. However, the sonographic findings of these lesions were often subtle, and careful scanning technique was needed for successful MRI–ultrasound correlation

(Ed..) this validates studies from Korea and Italy, published in Europe which showed that an US correlate was strongly associated with subsequent outcome of malignancy
