摘　　要：目的分析聚丙烯酰胺水凝胶注射隆乳术后并发症的MRI表现,并探讨其诊断价值。方法对20例26个出现并发症的乳腺及1例健康志愿者乳腺的MRI资料进行回顾性分析。结果感染及感染合并脓肿5例7个,表现为假体内团状长T1WI、长T2WI信号,T2WI信号较假体更高;无菌性炎症2例3个,假体包膜增厚,表现为稍长T1WI、等T2WI信号;硬结10例13个,表现为皮下、乳腺腺体内或胸大肌下的单个或数个固定的长T1WI、长T2WI信号;假体包膜破裂5例6个,表现为多发条块状、结节状长T1WI、长T2WI信号。诊断结果与临床和术后诊断结果符合。结论聚丙烯酰胺水凝胶注射隆乳术后并发症的MRI表现具有一定特点,诊断价值大,宜作为首选方法。Objective To analyze MRI findings and its clinical significance in complications of polyamide hydrogel injection for augmentation mammoplasty. Methods The complication findings of MR imaging in 20 cases with polyamide hydrogel injection for augmentation mammoplasty were retrospectively reviewed and analyzed. Results In 20 patients, 26 breasts suffered from complications, including infection (n=5) with pieces of long T_1and long T_2 signals, aseptic inflammation (n=2) with pieces of slight long T_1and moderate T_2 signals, hard nodule (n=10) with long T_1 and long T_2 signals, and rupture (n=5) with pieces and nodes of long T_1 and long T_2 signals on MR images. Conclusion MRI has the great diagnostic value in the detection of complications after polyamide hydrogel injection for augmentation mammoplasty, and it should be taken as the first diagnostic choice.
