Silicon appears as a T2 hypersignal, so it may be hard to differentiate it from lesions with a high T2 signal intensity (cysts) in breast imaging. To explore breast prostheses, dedicated silicon imaging sequences are used. They consist of STIR type fat signal suppression (inversion-recovery), and suppression of the water signal by selective saturation pulse centered on its resonance frequency peak.
