摘要
目的：探讨MRI在聚丙烯酰胺水凝胶（PAMHG）注射隆乳术后并发症中的诊断价值。方法：回顾性分析40例PAMHG注射隆乳患者的MRI图像及临床资料。结果：PAMHG在T1/TSE/SPIR图像上表现为与腺体相等信号，在T2/TSE/SPIR图像上表现为明显高信号。其中75.0%（30/40）的乳腺中PAMHG内见多发低信号间隔，80.0%（32/40）的乳腺中PAMHG未见光滑囊壁；20.0%（8/40）的PAMHG形态规则，可见边缘光滑的囊壁。PAMHG分布于皮下形成结节占22.5%（9/40），分布于腺体内形成硬结占37.5%（15/40），分布于胸大肌内呈带状占30.0%（12/40），胸腔内肋间肌间隙出现PAMHG游走占20.0%（8/40）。发现伴发导管内乳头状瘤及纤维瘤各1例，并发乳腺炎症3例。结论：轴位T1/TSE/SPIR、T2/TSE/SPIR和矢状位T2/TSE/SPIR对于PAMHG注射隆乳是一个很好的扫描序列，MRI对于手术前及手术后PAMHG分布及其并发症的评估具有较大的应用价值。
Abstract
Objective: To evaluate the clinical value of MRI in the diagnosis of the complications due to breast augmentation with polyacrylamide hydrogel(PAMHG). Methods: The MRI and clinical data of 40 patients who had breast augmentation with polyacrylamide hydrogel injection were retrospectively reviewed. Results: PAMHG showed iso-intensity compared with breast gland on T1/TSE/SPIR and hyperintensity on T2/TSE/SPIR. There are low signal septa within PAMHG in 75.0%(30/40) breast. There were 80.0%(32/40) PAMHG without capsule, 20.0%(8/40) with smooth and regular capsule. Subcutaneous lump of PAMHG was 22.5%(9/40), lump of that in the breast gland was 37.5%(15/40). Diffuse PAMHG along spatium intermusculare of pectoralis major was 30.0%(12/40), that along spatium intermusculare of intercostal muscle in the chest was 20.0%(8/40). One intraductal papilloma and one fibroadenoma in breast were observed in two patients. Breast infection were observed in three patients. All distributions of PAMHG and appearances of its complications on MRI were consistent with the results of the clinical. Conclusions: Axial T1/TSE/SPIR, T2/TSE/SPIR and sagittal T2/TSE/SPIR can be the optimized protocol of MRI examination for augmentation mammaplasty by injected polyacrylamide hydrogel. MRI is useful for preoperative assessment of the distribution of PAMHG and follow up after operation, and its complications.
