title: MR-guided vacuum-assisted breast biopsy using a non-titanium needle.
abstract: Biopsy is required for definitive diagnosis of lesions detected by magnetic resonance (MR) imaging that are suspicious or highly suggestive of malignancy. We performed MR-guided vacuum-assisted biopsy (VAB) using a commercially available biopsy device without a nonmagnetic needle in 5 patients with 5 lesions that were occult according to mammographic and sonographic findings. Complete removal was seen in 3 cases and partial removal in two. The VAB procedures were very well tolerated, and no important side effects were observed. MR-guided VAB can be performed safely with a nonmagnetic needle.
