MRI-Breast Implant Imaging: Signs of implant rupture
Figure 1. Intracapsular rupture in a 41-year-old woman with silicone implants who underwent MR imaging to evaluate for rupture. Axial T2-weighted (Ax T2) MR image shows evidence of bilateral intracapsular rupture with collapsed implants, including an intact fibrous capsule (yellow arrows); the linguine sign (red arrow) as demonstrated by the wavy lines made by the collapsed implant shell contained within the capsule; and the subcapsular line (purple arrows), noose (orange arrows), and keyhole (pink arrow) signs, which all show silicone on both sides of the envelope.
