Study of the Safety of MRI Scans in People Who Have Breast Tissue Expanders After Mastectomy

MRI scans will be performed on a 1.5T MRI scanner. Department of Radiology MRI SafetyGuidelines will be followed except regarding breast tissue expanders. Conventional MRIstudies will be performed using the standard of care clinical sequences.

Participants will fill out questionnaires before, immediately after, and approximately 3 months following the MRI examination +/- 1 month to evaluate for any pain or perceived changes with the breast tissue expander. The first questionnaire will obtain background participants information as well as establish a baseline pain level, the second questionnaire will evaluate any changes in pain after undergoing the MRI examination, and the last questionnaire will evaluate long term changes in pain. The patient reported outcome questionnaire will be optional at 3 months post-MRI +/-1 month.
