包囊挛缩是硅胶乳房植入体隆乳和乳房再造术中最常见和最令人沮丧的并发症之一。 由于缺乏量化挛缩的有效方法，对设计用于修改胶囊的方法的实验评价受到限制。 有人建议，测量包膜表面积将是量化包膜挛缩的最直接方法。 证明了使用磁共振成像计算种植体表面积的方法;使用几何已知表面积的硅胶体模验证了该方法。 还在人体受试者中测量了两种植入物的表面积;这是首次报告的体内植入物胶囊表面积测量。 根据平铺法计算表面积似乎是有效的，而周长法始终低估了胶囊表面积。 虽然临床相关性尚未得到证实，但希望进一步的包膜挛缩实验研究将纳入这种定量方法。
Capsular contracture has been among the most frequent and frustrating complications of augmentation and reconstructive mammoplasty with silicone breast implants. Experimental evaluation of methods designed to modify the capsule has been limited by the lack of an effective method for quantification of contracture. It has been suggested that measurement of capsule surface area would be the most direct way to quantify capsular contracture. A method using magnetic resonance imaging for calculation of implant surface area is demonstrated; validation of this method using silicone phantoms with geometrically known surface areas is presented. The surface areas of two implants were also measured in a human subject; this represents the first reported measurement of an implant capsule surface area in vivo. Calculation of surface area according to the tiling method appears to be valid, whereas the circumference method consistently underestimates capsule surface area. Although clinical correlation has not been proved, it is hoped that further experimental studies of capsular contracture will incorporate this quantitative method.
