Abstract

One intact and one ruptured single-lumen implant were surgically placed in a rabbit. Magnetic resonance (MR) imaging was performed before and after surgical removal, and the ruptured implant was imaged after removal of the implant shell. Multiple curvilinear hypointense lines (linguine sign) were present in the MR images of the ruptured implant and of the implant shell alone immersed in saline solution but not in the image of the free silicone. The collapsed implant shell in a ruptured silicone implant does cause the linguine sign.

摘要

将一个完整的和一个破裂的单腔植入物通过手术植入一只兔子体内。在手术取出前后进行磁共振（MR）成像，并且在取出植入物外壳后对破裂的植入物进行成像。在破裂的植入物以及单独浸泡在盐溶液中的植入物外壳的MR图像中存在多条曲线状低信号线（细面条征），但在游离硅胶的图像中不存在。破裂的硅胶植入物中塌陷的植入物外壳确实会导致细面条征。
