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.
