摘要：

背景：MRI检查可以早期确诊隐匿性骨折，低场强磁共振成像还具有专有线圈使图像更清晰的优点。
目的：分析低场强MRI在膝关节隐匿性骨折诊断中的应用价值。
方法：回顾性分析45例经手术、关节镜检查或临床证实的膝关节隐匿性骨折患者低场强MRI情况。
结果与结论：45例病例在X射线平片正侧位上均未见异常，而低场强MRI检查均呈现T1WI呈低信号，T2WI呈高信号，在STIR上病灶与正常骨组织的对比度更高，显示出不同部位隐匿性骨折的病变部位、范围及形态，其中34例伴交叉韧带、副韧带及半月板撕裂。提示低场强MRI能敏感显示创伤性膝关节隐匿性骨折的病变特点及严重程度，诊断准确，同时能发现膝关节韧带、肌腱及软骨的损伤，为首选检查手段。

Abstract:

BACKGROUND: MRI examination can be applied to the early diagnosis of occult fracture. Except for the characteristics of conventional MRI, low-field MRI has other advantages, such as a proprietary coil to make image clearer.
OBJECTIVE: To explore the value of low-field MRI for the diagnosis of occult traumatic fracture of the knee.
METHODS: Forty-five patients with occult traumatic fracture of the knee confirmed by using surgery, arthroscopy or clinical examination were examined by MRI.
RESULTS AND CONCLUSION: MR sequences included SE T1WI, GRE T2WI and STIR. The location, range, and morphology of fractures were analyzed. Thirty-four fractures in 45 cases were showed by MRI. Low-field MRI can sensitively display the characteristics and severity of occult traumatic fracture of the knee. Low-field MRI is accurate in diagnosis, and can find injuries of knee ligament, tendon, and cartilage.
