摘　　要：目的探讨隆乳术术后应用MRI评估假体状态的价值。方法回顾分析2011年3月~2015年12月间29例隆胸术后共58只乳腺的MR影像资料,评价MR图像中假体形态、位置、假体包膜状况,增强检查了解乳腺腺体病变状况及其与假体关系。结果 35只乳腺假体信号均匀,在短时间反转恢复序列(Short Time Inversion Recovery,STIR)上聚丙烯水凝胶假体比硅胶假体信号更高;11只假体轮廓完整,但明显变形、移位,其内可见条状影;12只乳腺假体轮廓不完整,包膜不连续,假体破裂散布于乳腺腺体结构内,其中3只假体突进胸大肌后及腋窝;42只乳腺增强扫描显示假体包膜比平扫更清晰,硅胶假体包膜比聚丙烯假体包膜更厚(P<0.01)。结论 MRI能全面显示置入假体的构成、形态、分布范围及术后乳腺腺体、胸壁病变状况,可以作为隆胸术术后评估的首选检查方法。Objective To explore the clinical value of MRI in evaluating breast prosthesis after augmentation mammoplasty. Methods The breast MRI data of 29 patients (58 breast prostheses) who underwent augmentation mammoplasty from March 2011 to December 2015, were retrospectively reviewed. The prosthetic shape, position and capsular of implant in MRI were evaluated. Then the mammary gland disease and its correlation with the prosthesis were also enhanced for examination.Results The signals of 35 breast prostheses were even, the signals of polyacrylamide hydrogel prosthesis on short time inversion recovery (STIR) sequence were higher than that of silicone prosthesis; 11prostheses had intact contour, but obviously deformation and transposing with strip shadow inside;12 prostheses were ruptured in contour with discontinuous capsular, in addition, prostheses fracturedand spread inside of the mammary gland section, 3 of them entered into ectopectoralis and armpits;the enhanced scanning of 42 breasts indicated implant capsular structures were more clear on volume image breast assessment (VIBRANT) than the plain scanning, and the implant capsular of silicone gel showed thicker than that of polyacrylamide hydrogel (P<0.01). Conclusion MRI could well display the formation, shape and distribution range of the breast prosthesis, along with the lesion of mammary gland and chest wall after surgery, which could be used as the first choice for postoperative evaluation of the augmentation mammoplasty.
