| 目的 总结小儿急性化脓性关节炎在MRI上的表现特点,评价MRI对化脓性关节炎的诊断价值。方法 10例临床证实为化脓性关节炎的患者均用Elscint Prestige 2.0T超导型MR机行横断面、矢状面和冠状面SE-T1WI、FSE-T2WI、FSE-PDWI及STIR序列的检查。在全面观察患病关节各部分MRI特点的基础上,重点分析关节软骨的改变。结果 10例化脓性关节炎中关节软骨异常改变7例,T2WI上信号升高,关节软骨与下方骨骺分界模糊5例,关节软骨表面不规则2例,关节软骨缺损1例。5例同时伴有干骺端骨髓炎、骨骺骨髓炎或脓肿,表现为T1WI上低信号,T2WI上高信号。2例干骺端见层状骨膜反应,5例关节周围软组织见长T1长T2异常信号。全部有关节腔积液。结论 MRI对关节软骨的评价有独特的优势,对判断化脓性关节炎的范围及严重程度亦有十分重要的价值。 |

| Purpose To summarize the MR imaging features of pediatric pyogenic arthritis and evaluate the diagnostic value of MR imaging in pediatric pyogenic arthritis. Methods Ten consecutive patients were imaged with Elscint Prestige 2.0T superconduct MR scanner. All patients were studied with SE-T1WI, FSE-T2WI, FSE-PDWI and STIR. Axial, saggital and coronal images were obtained. Analyze the all articular structure and pay attention to the changes of articular cartilage. Results The MR images of 10 cases showed effusion in articular spaces. Osteomyelitis or abscess of metaphysis and epiphysis occured in 5 cases with low signal intensity on T1WI and high signal intensity on T2WI. The changes of articular cartilage presented abnormality of signal intensity, bound between articular cartilage and undercartilage blured in 5 cases, irregular surface articular cartilage in 2 cases, defects of articular cartilage in 1 case. Two cases presented periosteal reaction, adjacent soft-tissue showed low signal intensity on T1WI and high signal intensity on T2WI in 5 cases. Conclusion MRI is the correct way to evaluate pyogenic arthritis, especially to evaluate articular cartilage. |
