Several techniques for measuring breast volume (BV) are based on examining the breast on magnetic resonance imaging. However, when techniques designed to measure total BV are used to quantify BV changes, for example, after fat grafting, a systematic error is introduced because BV changes lead to contour alterations of the breast. The volume of the altered breast includes not only the injected volume but also tissue previously surrounding the breast. Therefore, the quantitative difference in BV before and after augmentation will differ from the injected volume. Here, we present a new technique to measure BV changes that compensates for this systematic error by defining the boundaries of the breast to immovable osseous pointers. This approach avoids the misinterpretation of tissue included within the expanded boundaries as graft tissue. This new method of analysis may be a reliable tool for assessing BV changes to determine fat graft retention and may be useful for evaluating and comparing available surgical techniques for breast augmentation and reconstruction using fat grafting.
几种测量乳房体积(BV)的技术是基于在磁共振成像上对乳房进行检查。然而,当用于测量总BV的技术被用来量化BV变化时,例如在脂肪移植后,会引入系统误差,因为BV变化会导致乳房轮廓改变。改变后的乳房体积不仅包括注入的体积,还包括乳房之前周围的组织。因此,隆乳前后BV的定量差异将与注入体积不同。在此,我们提出一种测量BV变化的新技术,该技术通过将乳房边界定义为不可移动的骨性标志来补偿这种系统误差。这种方法避免了将扩大边界内包含的组织误判为移植组织。这种新的分析方法可能是评估BV变化以确定脂肪移植留存情况的可靠工具,并且可能有助于评估和比较使用脂肪移植进行乳房增大和重建的现有手术技术。
