摘要
目的探讨MRI与CT用于诊断强直性脊柱炎(AS)患者早期骶髂关节病变的应用价值。方法选取AS患者94例,分别进行MRI与CT检查,对比两种检查方式对病变程度与骨质异常情况的诊断结果。结果 MRI对Ⅰ级骶髂病变的检出率高于CT(P<0.05),两种检查方式对Ⅱ级以上病变的检出率无明显差异(P>0.05)。CT对骨质异常的检出率高于MRI(P<0.05)。结论 CT与MRI诊断AS骶髂关节病变各有优势,CT诊断骨质异常敏感性较高,MRI有利于早期Ⅰ级病变的发现。
Objective To explore the application value of MRI and CT in the diagnosis of sacroiliac joint lesions in patients with ankylosing spondylitis （AS）. Methods A total of 94 AS patients were selected. All cases received MRI and CT, and results of lesions＇ severity and abnormal bony changes diagnosed by two methods were compared. Results The detection rate for sacroiliac joint lesions at l degree of MRI was significantly higher than that of CT （P 〈0.05）, while no statistical difference was found between two methods in the detection rate for lesions at Ⅱ and above degree （P〉0.05）. CT had significantly higher detection rate than MRI for abnormal bony changes （P 〈0.05）. Conclusions CT and MRI have their respective advantages in the diagnosis of sacroiliac joint lesions in patients with ankylosing spondylitis. CT has higher sensitivity in the diagnosis of abnormal bony changes, while MRI is beneficial to find lesions at early I degree.
