MRI of the hip Joint in Ankylosing Spondylitis Show Involvement of Acute Inflammatory Changes in Benefits

目的探讨MRI在显示的强直性脊柱炎髋关节受累急性炎症改变中的优势。方法统计分析2012年1月-2014年1月我院收治的50例强制性脊柱炎患者的临床资料。结果 CT组25例患者中,5例患者髋臼及股骨头缘虫蚀状囊状骨质破坏,2例患者韧带骨化,2例患者关节间隙狭窄,3例患者关节缘骨质硬化;MRI组25例患者中,2例患者髋关节间隙模糊伴狭窄,14例患者关节面下方骨破坏,15例患者骨髓水肿,11例患者骨髓脂肪沉积,13例患者韧带附着点炎症,21例患者关节周围积液,12例患者关节滑膜异常强化;MRI组的髋关节异常检出率68%明显比CT组12%高（P〈0.05）;MRI组患者的诊断准确率92%（23/25）明显比CT组84%（21/25）高（P〈0.05）。结论 MRI在显示的强直性脊柱炎髋关节受累急性炎症改变中的优势较CT显著。

Objective To study the advantages of MRI in the display ofankylosing spondylitis hip involvement acute inflammatory changes. Methods The clinical data of 50 cases of patients with mandatory spondylitis in our hospital from January 2012 to January 2014 were statistically analyzed. Results In the CT group of 25 patients, 5 cases of＇patients with acetabular rim and femoral head worm-eaten cystic bone destnction, 2 cases with ligament , 2 cases with joint space narrowing, 3 cases with articular margin of bone sclerosis; In MIKI group with 25 cases, 2 cases with hip joint space narrowing thzzy, 14 cases with bone beneath the articular surface damage, 15 cases with bone marrow edema, 11 cases with bone marrow fat deposition, 13 cases with inflanunation of the ligament attachment points, 22 cases with the joints in surrounding fluid, 12 cases with synovial abnormal enhancement; the hip abnomaality detection rate of M1KI group was 68% and significantly higher than the CT group 12% （ P 〈 0.05） ; The diagnostic accuracy of MRI group 92% （ 23/25 ） was significant higher than the CT group 84% （ 21/25 ） （ P 〈 0.05 ） . Conclusion MRI has significant advantages over CT in the display of ankylosing spondylitis hip involvement acute inflammatory changes.
