When a suspicious finding is seen on breast MRI, high-resolution targeted US is performed to detect and evaluate the lesion, as well as to provide guidance for biopsy as needed. It is frequently possible to perform an ultrasound-guided biopsy instead of a more expensive and time-consuming MR-guided biopsy. However, one should be careful, because a malignant lesion detected by MRI may be subtle and less specific in appearance on US; therefore, careful ultrasound scanning is required.
