Initial Experience of Magnetic Resonance Imaging-guided Vacuum-assisted Breast Biopsy

Almost all mammary lesions are detected by a mammography and an ultrasound. However, a small part of lesions cannot be shown by only a magnetic resonance imaging (MRI). MRI-guided vacuum-assisted breast biopsy is a very useful means for the pathological diagnosis of these lesions. We performed MRI-guided vacuum-assisted breast biopsy to 4 patients with the lesions seen only by MRI. Biopsies were safely and easily performed using biopsy software (syngo BreVis). These biopsied specimens resulted cancer in 1, adenoma in 1 and benign lesions in 2. With an increase of the opportunity of MRI for the mammary lesions, we expect these lesions become increasingly large. We believe that MRI-guided vacuum-assisted breast biopsy will be an important diagnostic modality.
