摘　　要：目的分析隆乳材料及隆乳术后并发症的MR及全数字化乳腺钼靶摄影(FFDM)表现,观察MR及FFDM在乳腺假体植入术后评价中的价值。方法收集43例经MR和(或)FFDM检查的隆乳术后患者,分析不同类型假体的MR及FFDM表现。结果①水凝胶假体33例,MR明确显示66只乳房内液态假体的信号、形态、位置、假包膜及向周围组织渗漏情况;FFDM检查显示液态假体受腺体类型、注射位置、注射量及渗漏情况影响较大,部分病例显示不清。②自体脂肪3例:MR显示其中3只乳内见脂肪信号,1只乳感染并脓肿形成。FFDM显示6只乳房内见不同程度和形态的钙化;③硅胶假体3例:MRI可清楚显示其包膜及内部结构;④硅胶/水凝胶双假体4例:MR显示其中7只假乳包膜挛缩,周围散在液态假体信号。FFDM对两种假体内部及边缘情况显示欠佳。结论与FFDM比较,MR是评价乳腺假体植入术后情况的优选方法。Objective To observe MRI and FFDM appearances of breast implants and postoperative complications,and to assess the clinical value of MRI and FFDM.Methods Forty-three patients after augmentation mammoplasty underwent FFDM and MRI,the imaging manifestations of different replacements were analyzed respectively.Results ①In 33 patients after polyacrylamide hydrogel injection,MRI definitively showed the signal,shape,location,pseudo-capsule and peripheral leakage of liquid implants in all 66 breasts,while FFDM manifestations were influenced by the types of mammary glands,injected location,dose and leakage;②In 3 patients after auto-fat injection,fat signal was seen in 3 breasts and abscess was revealed in 1 breast on MRI,and FFDM showed different calcifications in 6 breasts;③In 3 patients after silicone implants,MRI showed the margin and capsule contracture of implants clearly;④In 4 patients after both silicone and polyacrylamide hydrogel replacements,MRI revealed that the capsule contracture shrunk in 7 breasts,surrounded by split polyacrylamide hydrogel,whereas the inner and bordering conditions remained unclear on FFDM.Conclusion Compared with FFDM,MRI is a superior method in accessing patients with augmentation mammoplasty.
