| 摘 要： | 目的:探讨低场强梯度回波短时反转恢复序列(GE STIR)在膝关节骨挫伤中的应用。方法:通过28例膝关节外伤病例在常规SE、TSE和GE STIR序列中的影像表现,分析GE STIR序列的优越性。结果:28例共32个骨挫伤病灶,T1W发现28个(占87.5%),T2W发现26个(占81.3%),在GE STIR序列病灶全部显示(100%)。结论:GE STIR序列对骨挫伤的敏感性较高,能显示微小的骨髓水肿、充血及骨小梁的微骨折,对膝关节外伤具有较高价值。

| Abstract: | Objective:To discuss the clinical application of magnetic resonance short time inversion recovery (STIR) in the diagnosis of bone contusion of knee joint.Methods:Twenty-eight cases of injury of knee joint were examed routinely with FSE series,SE series and GE-STIR series to analyze the superiority of STIR series.Results:Twenty-eight cases had 32 focuses of bone contusion.T_1W detected 28 (87.5%),T_2W detected 26 (81.3%),and all of the focuses were shown on the GE-STIR series (100%). Conclusion:GE-STIR series has high sensitivity for bone contusion,and it can show the tiny marrow edema and tiny fracture of trabeculae.It has high value for the diagnosis of injury of knee joint. |
