We measured T1 and T2 relaxation times of silicone breast implants and phantom materials that may mimic breast tissue at 3 Tesla. The characterization of the relaxivities of silicone breast implants provides the opportunity for improved pulse sequence design for the diagnosis of implant rupture, leak, deformity, or degradation. To the authors knowledge, this is the first report of MR relaxations times (T1 and T2) for silicone breast implants at 3 Tesla.
