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.
