Aims and objectives

MRI for evaluation of breast implants in suspected rupturehas become the investigation of choice.1 US is the most used imaging modality because, compared to MRI,it is fast, safe, portable, and inexpensive.2,3 However, MRIhas better sensibility and specificity than US and clinical examination for the diagnosis ofbreast implant rupture.1,3 The Centro Diagnostico Italiano in Milan has available MRI for evaluation of breast implants since 2012 and many patients consult our clinic as a referral center for this imaging modality. Therefore, we analyzedretrospectively breast MRI for suspected...

Methods and materials

Breast implants MRI images were performed with Philips Achieva 1,5 T magnetic field, without contrast media, with sagittal T2 STIR, axial water-suppression and silicone-suppression sequences. Patients that underwent to a MRI for suspected prosthesis rupture between January 2012 and December 2015 were included in this study. We included patients with both breast reconstruction after mastectomy and cosmetic surgery. Anamnesis and medical records were used to know time, type and position of implants. The study shown that 164 patients underwent to a MRI for suspected implant...

Results

Results Among the prosthesesstudied, 22% were diagnosed as broken by MRI(n=71), in 59 patients. 52% of broken implants were sub-pectoral, 45% sub-glandular and 4% dual-plane.The majority of implants were set 10 years before the MRI images (70%), with a median of 14 years. This value was 20 years for patients with bilateral rupture. We followed 30 patients with 24 breast implants surgically replaced. In the broken implants diagnosed group we have found 92,6% true positives. Traumatic events, especially car accidents, are decisive factor in 6%...

Conclusion

Our experience confirmed the potentiality of MRI to detect broken breast implants. Bilateral rupture is related to a remoter implant date. No relation between type, site and position were found.
