Summary: Breast implant displacement has been described as a significant risk following augmentation mammoplasty. Magnetic resonance imaging (MRI) is considered the method of choice for diagnosing implant complications, but it has its limits in assessing correct implant position and displacement. Motiva SmoothSilk/SilkSurface® Implants (MSS) are the first to incorporate a radio frequency identification device (RFID), which produces an imaging artifact in MRI sequences. Given the frequency of breast augmentation procedures and the recent US Food and Drug Administration prospective trial involving SS with RFID, further analysis of implant stability and diagnostic imaging methods to evaluate implant positioning is necessary. The objective of this study was to assess the use of MRI with this new RFID-containing implant as a new tool to assess correct implant positioning. The authors performed this technique in 5 patients (10 implants) undergoing primary breast augmentation or revision surgery with MSS implants (255–385 cc, mean = 325 cc). The average area and volume of the artifact were 15.7 cm2 and 31.75 cm3, respectively. All cases presented satisfactory results, with 1 case of implant displacement. Our clinical and radiological outcome demonstrated that RFID technology is a useful tool for correct visualization of the implant position and diagnosis of complications such as slight displacements or rotation. To our knowledge, this is the first RFID breast implant that has been objectively evaluated for MRI issues.
