摘要

目的探讨磁共振成像(MRI)对骨挫伤的诊断价值和意义，评价X 线、CT、MRI 诊断膝关节骨挫伤的效果。方法选取近年X 线平片未见膝关节骨折，而MRI 检查显示膝关节骨髓有异常改变的56个外伤病例，进行影像表现分析研究。结果 56 例 X 线平片均未见明确骨折征象，而 MRI 检查显示有骨挫伤

表现为 T

WI短TI反转恢复序列（short TI inversion recovery

STIR）病变区呈高信号

WI 呈稍低信号

有膝关节骨挫伤的部分病例还伴有前后交叉韧带、内外侧副韧带、内外侧半月板损伤及创伤性滑膜炎等表现。结论 MRI 能早期显示骨挫伤及隐性骨折

如患者外伤后 X 线平片或CT 未见骨折

外伤部位持续疼痛并伴有软组织肿胀

不能承受重力

应做 MRI 检查；脂肪抑制技术STIR及化学位移脂肪成像（Chem-Sat）对显示骨挫伤的敏感性较高

能显示细微的骨髓水肿、充血及骨小梁的微骨折

对发现骨外伤的隐性损伤具有较高的诊断价值。

Abstract

Objective To study the significance of MRI and to evaluate the effectiveness of X-ray film

and MRI in the diagnosis of bone contusion. Methods Fifty-six cases of abnormal marrow signal in MRI but without fracture in knee in X-ray plain film were respectively analyzed. Results No obvious bone fracture sign was observed in X-ray film in all cases but bone contusion was found in MRI

which showed as high signal intensity on T

WI Short TI Inversion Recovery(STIR) and slightly low signal on T

WI. Anterior and posterior cruciate ligament

medial and lateral collateral ligament

medial and lateral meniscus and synovium injuries were also fo

und in some cases of knee contusion. Conclusion Bone contusion could be detected in MRI in early stage. So if bone fracture was not found in X-ray plain film or CT

but ache and swelling in traumatic area is persistent

it is recommended to perform MRI examination. STIR and Chem-sat series are sensitive in displaying slight bone marrow swelling

congestion

slender fracture of bone trabecula and are of great importance in diagnosing injuries in bone trauma.
