High-resolution solid-state 29Si NMR spectra of four (Y, 8, e~ and e) polymorphs of Ca2SiO 4 have been measured. The isotropic silicon 29Si chemical shifts lie between -73.5 and -70.1 ppm, and increasing coordination number of calcium leads to low-field 29Si shifts. The 29Si shifts in combination wi

## Abstract We have used ^29^Si solidβstate nuclear magnetic resonance (NMR) spectroscopy to study the chemical structure of the silicone gels in virgin and explanted breast prostheses. Despite evidences of alteration in the morphological appearance of the silicone gel inside the breast prosthesis,
