聚丙烯酰胺水凝胶（PAHG）的体积测量对手术计划是有用的。它不仅是隆胸术前评价的重要因素，而且可能直接影响隆胸术后的乳房形态。本研究的目的是评估磁共振成像（MRI）是否能够提供注射PAHG体积的精确计算。将随机选择的10名患者的MRI扫描输入Mimics软件。对注射的PAHG进行重建，得到PAHG的体积。为了评估该技术的精确性和观察者独立性，三位整形外科医生使用该方法估计了PAHG的体积。3个观察者计算的PAHG注射量差异无统计学意义（P=0.173）。观察者内相关系数为0.964，表明该方法计算PAHG体积的精度和可行性。使用MRI结合Mimics软件计算PAHG体积可能在术前手术计划中具有显著的临床益处。
Volumetric measurement of polyacrylamide hydrogel (PAHG) is useful for surgical planning. It is not only a significant factor in the preoperative evaluation of breast augmentation, but may also directly affect the postoperative shape of the breast. The objective of the present study was to evaluate whether magnetic resonance imaging (MRI) is able to provide precise calculations of injected PAHG volumes. MRI scans of ten randomly selected patients were imported to Mimics software. The volumes of PAHG were obtained following the reconstruction of the injected PAHG. In order to assess the precision and observer independency of the technique, the volumes of PAHG were estimated by three plastic surgeons using this method. No significant differences were identified among the PAHG injection volumes calculated by the three observers (P=0.173). The intra-observer correlation coefficient was 0.964, which indicates the precision and feasibility of this method for calculating the volume of PAHG. The use of MRI in combination with Mimics software to calculate PAHG volumes is likely to be of significant clinical benefit in preoperative surgical planning.
