| 摘 要： | 目的:探讨色素沉着绒毛结节性滑膜炎(PVNS)的MRI表现。方法:回顾性分析17例经病理证实的膝关节PVNS患者,总结其MRI表现。结果:17例膝关节PVNS在MRI各序列上均具有特征性表现,滑膜弥漫性增厚,可见含铁血黄素的结节,T1WI、T2WI均呈低信号。结论:PVNS在MRI表现中具有特异性征象,因此MRI对于PVNS的诊断价值是其它影像检查手段无法比拟的。

| Abstract: | Objective:To investigate MRI features of pigmented villonodular synovitis.Methods:MRI findings of 17 patients with pathologically-proved pigmented villonodular synovitis were retrospectively analyzed.Results:Typical feature can be seen on every alignment of MRI scan in the 17 patients including nodular synovitis prolifetation,typical for hemosiderin deposition,iso-low signal on T1WI and T2WI.Conclusion:PVNS has typical feature in MRI scan.Contrasting the other diagonosis of image,MRI is of great value in diagnosing PVNS. |
