摘要:
目的 探讨应力性骨折诊断的磁共振影像表现，分析磁共振成像（MRI）T1WI序列在膝关节应力性骨折中的应用价值。方法 选取2016年1月~2019年12月经临床及随访检查确诊应力性骨折患者34例，行膝关节磁共振检查35例（1例为双侧），按照磁共振序列分为冠状位、矢状位T1WI组和冠状位T2WI、矢状位PD压脂组，分析两组磁共振差异进行。结果 34例患者中膝关节表现为应力性损伤1例，35例应力性损伤均有骨髓水肿信号，其中2例应力性损伤3级，33例应力性损伤4级；两组骨折线走行与皮质垂直或轻度成角；冠状位、矢状位T1WI骨折线显示率（100.00%）高于冠状位T2WI、矢状位PD压脂组骨折线显示率（93.94%）。结论 MRI能显示细微的应力性损伤，并能清晰显示骨折线及软组织情况，冠状位或矢状位T1WI观察骨折线优于T2WI、PD压脂序列。
Abstract:
Objective To explore the magnetic resonance imaging manifestation of stress fracture diagnosis and analyze the application value of magnetic resonance imaging T1WI sequence in knee stress fracture.Methods 34 patients with stress fracture diagnosed by clinical and follow-up examination from January 2016 to December 2019 were selected, 35 patients of knee joint magnetic resonance examination (1 case was bilateral), according to the magnetic resonance sequence, it was divided into coronal, sagittal T1WI group and coronal T2WI, sagittal PD lipid pressure group, analysis of the difference between the two groups of magnetic resonance.Results Among the 34 patients, the knee showed 1 case of stress injury, 35 cases of stress injury had bone marrow edema signal, 2 cases of stress injury level 3, 33 cases of stress injury level 4; the fracture line of the two groups was perpendicular to the cortex or slightly angled; the fracture rate of the T1WI fracture line in the coronal and sagittal positions (100.00%) was higher than that in the lipid pressure group of the coronary T2WI,the fracture line display rate (93.94%) in the sagittal PD lipid pressure group.Conclusion MRI can show subtle stress injury, and can clearly show the fracture line and soft tissue, coronal or sagittal T1WI observation fracture line is better than T2WI, PD lipid sequence.
