Lesion identification in MR-guided biopsy exams can be hampered by many factors, including large deformations and limited tissue perfusion due to breast compression. Multiple post-contrast scans, image subtraction and maximum intensity projection map generation may be needed to relocate the lesion. This preliminary study suggests that non-rigid registration between the (uncompressed breast) pre-biopsy series and the (compressed breast) biopsy series may facilitate fast and accurate lesion (re)localization, even with limited/absent lesion enhancement.
