多模态影像学检查在诊断早期强直性脊柱炎骶髂关节疾病中的效果

目的:探究在早期强直性脊柱炎骶髂关节疾病诊断中不同放射影像学检查方法的应用效果。方法:抽取2018年5月-2020年1月本院收治的早期强直性脊柱炎骶髂关节疾病患者65例作为研究对象,所有患者均开展X线、CT、MRI影像学检查,对比三种不同影像学检查方法的检出率、影像学特征。结果:X线、CT、MRI检出率分别为38.46%(25/65)、60.00%(39/65)、76.92%(50/65),检出率相比,MRI、CT明显高于X线,P<0.05;X线、CT、MRI影像学特征,发现关节间隙出现不同的异常,如关节面出现侵蚀、骨质囊变现象,关节面下骨质出现硬化与关节软骨出现肿胀,其中MRI、CT检查,阳性率高于X线,P<0.05。而对于软组织肿胀、骨髓水肿、滑膜炎症、关节滑膜增厚等现象,只能通过MRI检查才能诊断。结论:在早期强直性脊柱炎骶髂关节疾病诊断中,X线、CT、MRI影像学检查均具有一定的指导意义,而MRI不仅可以提高检出率,还能准确反映微小病灶及其软组织病变,对于早期发现骶髂关节炎值得推荐。

Multimodal Imaging in the Diagnosis of Early Ankylosing Spondylitis Sacroiliac Joint Disease

Objective:To explore the application effect of different radiological examination methods in the diagnosis of sacroiliac joint disease in early ankylosing spondylitis.Methods:65 patients with sacroiliac joint disease of early ankylosing spondylitis admitted to our hospital from May 2018 to January 2020 were selected as the research objects.All patients underwent X-ray,CT,MRI and other imaging examinations,and the detection rate and imaging characteristics of three different imaging examination methods were compared.Results:The detection rates of X-ray,CT and MRI were 38.46%(25/65),60.00%(39/65)and 76.92%(50/65),respectively.The detection rates of MRI and CT were significantly higher than that of X-ray(P<0.05).The imaging features of X-ray,CT and MRI showed different abnormalities in joint space,such as joint surface erosion,bone cyst,bone sclerosis and articular cartilage swelling 1.The positive rate of CT was higher than that of X-ray(P<0.05).For soft tissue swelling,bone marrow edema,synovial inflammation,joint synovial thickening and other phenomena,can only be diagnosed by MRI.Conclusion:In the diagnosis of sacroiliac joint disease in early ankylosing spondylitis,X-ray,CT,MRI and other imaging examinations have certain guiding significance,and MRI can not only improve the detection rate,but also accurately reflect the small lesions and soft tissue lesions,which is recommended for early detection of sacroiliac joint disease.
