MR-Guided vacuum biopsy of 206 contrast-enhancing breast lesions.
Rofo. 2002 Jan; 174(1):88-95.ROFO

Abstract

PURPOSE

To determine the accuracy and clinical use of MR-guided vacuum biopsy (VB) of enhancing breast lesions.

MATERIAL AND METHODS

254 lesions were referred to MR-guided vacuum-assisted breast biopsy. In 43 (16 %) patients the indication was dropped because the lesions could not be identified at the time VB was scheduled. This was due to hormonal influences (n = 37), to too strong compression (n = 3) or to misinterpretation of the initial diagnostic MRI (n = 3). In 5 cases (2 %) VB was not performed due to obesity (n = 2); problems of access (n = 2) or a defect of the MR-unit (n = 1). VB was performed on altogether 206 lesions. In 4 cases (2 %) VB was unsuccessful. This was immediately realized on the post-interventional images. Thus a false negative diagnosis was avoided. Verification included excision of the cavity in cases with proven malignancy or atypical ductal hyperplasia (ADH) and (for benign lesions) retrospective correlation of VB-histology with pre-and postinterventional MRI and subsequent follow-up.

RESULTS

51/202 successful biopsies proved malignancy. In 7 cases ADH and in 144 cases a benign lesion was diagnosed. One DCIS was underestimated as ADH. All other benign or malignant diagnoses proved to be correct.

CONCLUSION

MR-guided VB allows reliable histological work-up of contrast-enhancing small lesions which are not visible by any other modality.
