【摘要】：目的:探讨磁共振压脂序列在检查幼年型关节炎中的应用价值。方法:选择1 131例幼年型关节炎患者的1 601个有症状关节行磁共振普通T1加权像(T1 weighted imaging,T1WI)及T2加权像(T2 weighted imaging,T2WI)序列与精确频率反转恢复(spectral presaturation attenuated inversion recovery,SPAIR)T2压脂序列检查。所有图像由2名高年资放射科医生及1名小儿风湿免疫科医生独立进行评估,确定关节组织病变的形态和程度,当3名医师意见不一致时,通过讨论达成一致。结果:磁共振异常发现847个,占全部检查的52.9%;普通序列异常发现409个,占异常发现的48.3%;压脂序列异常发现816个,占异常发现96.3%。其中关节积液占异常发现的59.5%,骨髓水肿占异常发现的39.7%。压脂序列对幼年型关节炎的骨髓水肿、关节积液、滑膜增厚、软骨损伤检出率高于普通序列(P0.05),普通序列的骨侵蚀检出率高于压脂序列(P0.05),两种序列对关节囊肿的检出率差异无统计学意义(P0.05)。结论:在幼年型关节炎磁共振检查中加用压脂序列可明显提高影像学阳性检出率;磁共振压脂序列对幼年型关节炎早期病理变化如骨髓水肿和关节积液等检出率高,可为早期诊断幼年型关节炎提供依据。
[Abstract]:Objective: to evaluate the value of Mr lipid-pressing sequence in the diagnosis of juvenile arthritis.All images were independently evaluated by 2 radiologists and 1 pediatric rheumatoid immunologist to determine the shape and extent of joint tissue lesions. When three physicians were not in agreement with each other, an agreement was reached through discussion.Results: there were 847 abnormal magnetic resonance findings (52.9%), 409 normal sequence anomalies (48.3%), 816 abnormal blood pressure sequences (96.33%).Joint effusion accounted for 59.5% of abnormal finding, bone marrow edema accounted for 39.7% of abnormal detection.Effects of lipid compression sequence on bone marrow edema, joint effusion, synovial thickening in juvenile arthritis,The detection rate of cartilage injury was higher than that of common sequence (P 0.05), and the detection rate of bone erosion in common sequence was higher than that of fat compression sequence (P 0.05). There was no significant difference between the two sequences in the detection rate of articular cysts (P 0.05).Conclusion: the positive rate of MRI in juvenile arthritis can be improved by adding lipid compression sequence to juvenile arthritis, and the positive rate of MRI in early pathological changes of juvenile arthritis, such as bone marrow edema and joint effusion, is high.It can provide evidence for early diagnosis of juvenile arthritis.
