MSCT、MRI及X线诊断强直性脊柱炎骶髂关节病变价值比较

Comparison on the Diagnostic Value of MSCT,MRI and X-ray in Sacroiliac Joint Lesions of Ankylosing Spondylitis

目的分析MSCT、MRI及X线诊断强直性脊柱炎骶髂关节病变的影像学价值。方法选择2017年1月至2019年6月期间接受治疗的已确诊为强直性脊柱炎骶髂关节的患者80例作为研究对象,行MSCT、MRI及X线平片检查,观察并分析其影像学特点、分级情况及表现结果,对比三种检查方式的诊断价值。结果MSCT的总检出率(83.75%)和MRI的总检出率(93.75%)显著高于X线平片(53.75%,P<0.05);MRI的总检出率显著高于MSCT(P<0.05);MSCT、MRI和X线平片均可检查出关节面侵蚀、关节面下骨质囊变、关节间隙狭窄或增宽、骨质增生硬化、关节强直;仅MSCT和MRI可以检查出软组织肿胀,X线无法检出。结论MSCT、MRI及X线平片对于强直性脊柱炎骶髂关节病变的检出均有一定的诊断价值,其中MRI的检出率最高且能够更好地反映微小病变及软组织病变。

Objective To analyze the imaging value of MSCT,MRI,and X-ray in sacroiliac joint lesions of a n kylosing spondylitis(AS).Methods Eighty patients confirmed with sacroiliac joint lesions of AS treated from January 2017 to June 2019 were enrolled as the research objects.All underwent MSCT,MRI and X-ray examination.The imaging features,classification,and findings were observed and analyzed.The diagnostic value of the three methods was compared.Results The total detection rate of MSCT and MRI was significantly higher than that of X-ray(83.75%,93.75%vs.53.75%)(P<0.05).The total detection rate of MRI was substantially higher than that of MSCT(P<0.05).The joint erosion,subarticular bone cyst degeneration,stenosis or widening of joint space,hyperostosis osteosclerosis and ankylosis could be detected by MSCT,MRI,and X-ray.The soft tissue swelling could be detected out only by MSCT and MRI.Conclusion MSCT,MRI,and X-ray are of particula r diagnostic value in sacroiliac joint lesions of AS.Among them,the detection rate of MRI is the highest,reflecting lesions and soft tissue lesions.
