Ruptured breast implants, MRI
Ruptured breast implants. Coloured magnetic resonance imaging (MRI) scan of ruptures in both of a woman's breast implants (red). These are intracapsular ruptures, the most common type. The material within the implants (either saline or silicone) has breached the implant membrane, but not the capsule of fibrous scar tissue (green) that forms around the implant after surgery. This type of rupture is characterised by the 'linguini sign', thin curvy lines (blue) seen within the implant on MRI scans. These lines are the sections of the implants' membranes that have collapsed. Approximately fifty per cent of all implants rupture after twelve years.
