MRI对隆乳手术术后患者的诊断价值

目的:探讨隆乳术后并发症MRI影像学特征及不同影像技术的诊断价值.方法:对32例63只隆乳术后出现症状的乳房行1.5T MRI平扫、3D FSE脂肪抑制水成像及VIBRANT动态增强扫描.结果:本组28例55只乳房行注射式水凝胶隆乳术,47只假体外漏,双乳不对称4例,1例2只为感染,1例1只为假体内出血,3例3只为腺体病变.1例行双侧乳房内自体脂肪注射术,乳房下部可见较多脂肪团块.3例行双侧乳房硅胶假体植入术,1例1只盐水假体变形,1例1只硅凝胶假体外漏.上述影像学表现均与取出术中结果相符.结论:MRI对诊断隆乳术后外漏并发症有着重要的价值,VIBRANT序列有助于诊断感染及腺体病变,3D FSE脂肪抑制水成像序列对水凝胶和硅胶盐水假体的整体显示有显著的优势.

Diagnostic Value of Magnetic Resonance Imaging in Postoperative Complications of Breast Augmentation

Objective:To study the magnetic resonance imaging features of postoperative complications of breast augmentation and the diagnostic value of different imaging techniques.Methods:A 1.5T HD MR scanner was used to perform plain,VIBRANT contrast enhanced scanning and 3D/FRFSE magnetic resonance hydrography in 63 breasts of 32 patients with breast augmentation.Results:55 breasts in 28 patients were treated with polyacrylamide hydrogel injection.In 47 breasts,the implants were shown as irregular lumps of gel freely sited in pectoral muscles,mammary glands,subcutaneous fat tissue and so forth.The technique of self-fat injection into both breasts was performed in 1 case and the result of fatty masses was detected in the inferior portions of both breasts.Silicone implants were implanted into both breasts in 3 cases.A saline-filled implant was found in 1 breast of 1 of the 3 cases and another 1 case with silicone gel leaking out in 1 of the breasts was detected.The above MR signs were all well consistent with the surgical findings.Conclusion:Breast magnetic resonance imaging played an essential role in the diagnosis of postoperative complications of breast augmentation;the VIBRANT technique was useful in the demonstration and diagnosis of infection as well as the pathological changes of the mammary glands;3D/FRFSE magnetic resonance hydrography technique revealed the potentials of demonstrating the hydrogel and the whole view of saline filled silicone gel prosthesis.
