1. Dual-energy CT performed at 100 and 140 kV allows identification of silicone within breast implants and also extra-capsular silicone within the breast tissue and in axillary nodes with dedicated breast MRI as the reference standard. 2. CT can evaluate for collapsed silicone envelopes within the fibrous capsule seen with intracapsular rupture. 3. CT allows evaluation of level 1 and extra-axillary nodes which may not be well visulaized on dedicated breast MRI.

A. Description of the different types of silicone implants  B. Outline of physics of dual-energy CT for identificaiton of silicone C. Comparison of DECT silicone specific images with gold standard MRI for evaluation of intra and extracapsular rupture of silicone implants. D. Examples of US evaluation of silicone implants and extracapsular silicone within the breasts and axillary ndoes - snowstorm appearance - with DECT comparison. E. Review of recommendations of the FDA for follow-up of newly placed silicone implants.
