There are anecdotal reports of tissue expander damage or
dislodgement during MRI and are currently labeled MR
Unsafe. At our institution, abdomen-pelvis MRI/MRA is
frequently requested in these patients to map perforator
vessels supplying abdominal fat/skin to plan autologous
breast reconstruction. Since these tissue expanders will
be removed at the time of breast reconstruction,
surgeons performing these operations feel that the
benefit of pre-operative MRA outweighs the risk of any
implant migration or local tissue damage potentially
caused by MRI. In this study we retrospectively review
breast tissue expander safety for 73 patients who
underwent abdominal and pelvic MR for autologous breast
reconstruction.
