MRL GUIDED BIOPSY OF SUSPECT BREAST-LESIONS WITH A SIMPLE STEREOTAXICADD-ON DEVICE FOR SURFACE COILS

A guiding attachment is described that transforms a conventional magne tic resonance (MR) imaging surface coil into a stereotaxic biopsy unit . Eight patients, aged 38-66 years (mean, 54 years), with suspect brea st lesions detected exclusively at contrast material-enhanced MR imagi ng underwent MR-guided needle biopsy with this unit Diagnostic materia l was successfully aspirated in all patients (four carcinomas, three f ibroadenomas, and one intraductal hyperplasia), and the diagnosis was subsequently confirmed at surgical biopsy. This technique promises to increase the diagnostic specificity for lesions seen solely at MR imag ing.
