Introduction
The sensitivity of MRI for invasive cancer and DCIS far exceeds that of XRM, and a substantial proportion of these malignant lesions either cannot be seen at all on TUS or cannot be identified with sufficient confidence to allow biopsy. Accordingly, a means of performing MRI-guided tissue sampling is an essential part of any breast MRI service. Frequently, MRI-only lesions (not seen on TUS or XRM) are foci (< 5 mm), small masses (< 10 mm) or focal areas of ductal non-mass enhancement, which can be challenging targets for the relatively small tissue volumes yielded by 14-gauge CNB. Accordingly, the more robust biopsy options of MRI-guided hookwire localization or VAB are preferred.
