摘要
目的探讨MRI影像学评价在急性化脓性骨髓炎早期诊断中的应用价值,为临床早期诊断及治疗提供依据。方法对22例急性化脓性骨髓炎患者于发病后2～14d,分别行X线平片、CT、MRI检查。结果本组患者X线片检查结果显示,发病10d内仅见软组织肿胀,14d后2例可见干骺端骨质模糊、稀疏;CT检查结果显示,发病10d内仅见软组织肿胀,10d后可见骨髓密度降低,骨小梁模糊不清,肌间脂肪间隙变薄甚至消失;MRI结果显示,发病3d内仅见软组织界线不清、T2WI呈略高信号,3d后骨髓内可见异常信号,表现为T1WI信号稍减低、T2WI信号稍增高,在脂肪抑制序列上更清楚,且随病程延长逐渐明显。结论 MRI影像学评价优于其他检查方法,可用于急性化脓性骨髓炎的早期诊断。
OBJECTIVE To evaluate MRI imaging evaluation in the early diagnosis of acute suppurative osteomyelitis.METHODS A total of 22 cases of acute suppurative osteomyelitis patients were enrolled the study,the line X-ray,CT,and MRI examination were performed 2 to 14 days after onset of symptoms.RESULTS The X-ray examination result showed that the soft tissue swelling was only detected within 10 days,2 cases could be seen with visible soft tissue swelling,and the vague and sparse metaphyseal bone 14 days after the incidence.While the CT examination result revealed that the soft tissue swelling was only detected within 10 days of the onset,with the bone marrow density deceasing,trabecular bone fuzzy,fat space between the muscle thinning,or even disappearing.MRI result indicted that the soft tissue boundaries were unclear,with T2WI slightly higher signal,abnormal signal in the bone marrow seen within 3 days,presenting as T1WI signal decreasing slightly and T2WI signal slightly ascending,which was more clear on fat suppression sequence,and it became clear along with the extension of the disease course.CONCLUSION MRI imaging evaluation is superior to other tests and can be used for the early diagnosis of acute suppurative osteomyelitis.
