MRI-guided breast biopsy based on diffusion-weighted imaging: a feasibility study

Objectives This study evaluated the feasibility of DWI for lesion targeting in MRI-guided breast biopsies. Furthermore, it assessed device positioning on DWI during biopsy procedures. Methods A total of 87 biopsy procedures (5/87 bilateral) consecutively performed between March 2019 and June 2020 were retrospectively reviewed: in these procedures, a preliminary DWI sequence ( b = 1300 s/mm 2 ) was acquired to assess lesion detectability.
