外伤性骨髓水肿MRI诊断分析

Analysis of magnetic resonance imaging diagnosis in traumatic marrow edema

目的:探讨MRI检查诊断外伤性骨髓水肿的价值。方法:分析21例肢体外伤后X线摄片或CT扫描无异常征象患者的MRI表现。结果:21例共有30处外伤性骨髓水肿病灶,T1WI发现26个,T2WI发现19个,STIR序列显示全部病灶。结论:MRI检查对外伤性骨髓水肿具有较高的诊断价值,STIR序列显示效果最佳。

Objective：To improve the level of MRI diagnosis in traumatic marrow edema. Methods. The MRI of 21 patients with traumatic limbs, but without abnormal findings by X-ray or CT scan was analyzed. Results： There were 30 traumatic medulla oedema focuses in the 21 patients. T1 WI detected 26 （ 86.7 % ） and T2 WI detected 19 （63.3 % ）, and all of the focuses were shown on the STIR series（ 100% ）. Conclusions： MRI in traumatic medulla oedema could improve the diagnosis value and clinical significance.
