MRI-guided vacuum-assisted breast biopsy performed at 3 T with a 9-gauge needle: preliminary experience

The purpose of this study was to test the feasibility of 3-T vacuum-assisted large-bore core biopsy of lesions detected with MRI of the breast. Our preliminary experience revealed that 3-T MRI-guided vacuum-assisted biopsy is a safe and effective interventional method that enables accurate biopsy of lesions identified with a 3-T MRI system. Artifacts on 3-T images did not result in failed biopsy; therefore, 3-T MRI systems can be used reliably for both diagnostic and interventional breast studies.
