ABSTRACT In 2006, the U.S. Food and Drug Administration recommended screening of all women with silicone gel breast implants with magnetic resonance imaging 3 years after implantation and every 2 years thereafter to assess their integrity. The cost for these serial examinations over the lifetime of the breast implants is an added burden to insurance payers and to women. The authors performed an economic analysis to determine optimal screening strategies by considering the diagnostic accuracy of the screening tests, costs of the tests, and subsequent implant removal.
The authors determined aggregate/pooled values for sensitivity and specificity of the screening tests of ultrasound and magnetic resonance imaging in detecting silicone breast implant ruptures from the data obtained from published literature. They compiled costs, based on Medicare reimbursements for 2011, for the following elements: imaging modalities, anesthesia, and three surgical treatment options for detected ruptures. A decision tree was used to compare three alternate screening strategies of ultrasound only, magnetic resonance imaging only, and ultrasound followed by magnetic resonance in asymptomatic and symptomatic women.
The cost per rupture of screening and management of rupture with ultrasound in asymptomatic women was $1090; in symptomatic women, it was $1622. A similar cost for magnetic resonance imaging in asymptomatic women was $2067; in symptomatic women it was $2143. A similar cost for ultrasound followed by imaging in asymptomatic women was $637; in symptomatic women, it was $2908.
Screening with ultrasound followed by magnetic resonance imaging was optimal for asymptomatic women, and screening with ultrasound was optimal for symptomatic women.

    ABSTRACT: Oncologic, reconstructive, and cosmetic breast surgery has evolved in the last 20 years. Familiarity with cutting-edge surgical techniques and their imaging characteristics is essential for radiologic interpretation and may help avert false-positive imaging findings. Novel surgical techniques include skin- and nipple-sparing mastectomies, autologous free flaps, autologous fat grafting, and nipple-areola-complex breast reconstruction. These techniques are illustrated and compared with conventional surgical techniques, including modified radical mastectomy and autologous pedicled flaps. The role of magnetic resonance (MR) imaging in surgical planning, evaluation for complications, and postsurgical cancer detection is described. Breast reconstruction and augmentation using silicone gel-filled implants is discussed in light of the Food and Drug Administration's recommendation for MR imaging screening for "silent" implant rupture 3 years after implantation and every 2 years thereafter. Recent developments in skin incision techniques for reduction mammoplasty are presented. The effects of postsurgical changes on the detection of breast cancer are discussed by type of surgery. ©RSNA, 2014.

    ABSTRACT: Silicone breast implants are commonly used in breast surgery, either for esthetic or reconstructive procedures. There have been several case reports of silicone migration, with or without implant rupture. One of the possible consequences of such migration is the formation of siliconomas.We performed an exhaustive review of the literature, which is relatively scarce and disperse, on the diagnosis, treatment, and possible complications of this entity and its differential diagnosis with breast cancer and axillary metastasis. This article also discusses the latest available information and recommendations on Poly Implant Prostheses. Due to their characteristics, these implants show a high frequency of rupture, silicone migration, siliconomas, and related complications.The rate of silicoma formation is unknown but is strongly associated with implant rupture and subsequent gel migration. The breast implants of choice are those made of highly cohesive silicone gel. The most important problem associated with siliconomas is the differential diagnosis with breast cancer and axillary metastasis, in which magnetic resonance is the gold standard diagnostic technique.Once a silicoma has been diagnosed, the most suitable option is its surgical removal and implant replacement.

    ABSTRACT: Implant rupture is a common late complication of breast implant procedures. Ruptures are often silent and difficult to diagnose clinically. This review demonstrates normal appearances and sonographic signs of implant rupture. Breast sonologists should be aware of these signs and pitfalls in interpretation when imaging breast implants.
