Autologous lipotransfer is becoming more and more popular in plastic surgery. Until now the rate of fat survival was merely estimated by the surgeon and no proven data exist. To assess this surgical method a reproducible and exact tool for volume analysis is necessary.
The volume of silicone implants was calculated in six healthy patients with silicone breast augmentation using the BrainLab(c) I Plan Software. In the same technique volumetry was performed in 10 patients before and six months after autologous lipotransfer using the water-jet assisted liposuction (BEAULI) to harvest the fat tissue.
Comparison of the implant volumes calculated with MRI volumetry with the official volumes given by the manufacturer showed a very low mean deviation of 2.1+/-1.5%. Preoperative and postoperative MRI volumetry in patients after autologous lipotransfer revealed a mean volume augmentation of 147+/-18 mL. In these patients 72+/-11% of the transplanted fat tissue persisted in the area of injection six month after surgery.
MRI volumetry is a useful tool for the fast, exact and reproducible volume analysis of breast tissue. Especially after autologous lipotransfer, where MRI examinations are performed on a regular basis to exclude possible complications, the use of these data to evaluate the rate of fat tissue survival is appealing and due to the high exactness of the method also reasonable.
自体脂肪移植在整形手术中越来越受欢迎。到目前为止，脂肪存活率仅由外科医生估计，尚无确凿数据。为了评估这种手术方法，需要一种可重复且精确的体积分析工具。
使用BrainLab(c) I Plan软件计算6例接受硅胶隆胸的健康患者的硅胶植入物体积。采用相同技术，对10例接受水刀辅助吸脂（BEAULI）获取脂肪组织进行自体脂肪移植的患者，在术前及术后6个月进行容积测量。
通过MRI容积测量法计算的植入物体积与制造商提供的官方体积相比，平均偏差非常低，为2.1±1.5%。自体脂肪移植患者术前和术后的MRI容积测量显示平均体积增加了147±18 mL。在这些患者中，术后6个月，72±11%的移植脂肪组织在注射部位留存。
MRI容积测量是一种用于乳腺组织快速、精确且可重复的体积分析的有用工具。特别是在自体脂肪移植后，定期进行MRI检查以排除可能的并发症，利用这些数据评估脂肪组织存活率很有吸引力，而且由于该方法的高精确性，也是合理的。
