强直性脊柱炎骶髂关节病变CT与MRI诊断比较

Comparison of CT and MRI in the diagnosis of sacroiliac joint lesions in patients with ankylosing spondylitis

目的:探究对强直性脊柱炎骶髂关节的病变CT检查和MRI检查的结果的比较。方法:收治强直性脊柱炎骶髂关节病变患者32例,对所有患者的CT检查和MRI检查的临床特点进行统计和分级。结果:对于Ⅰ级强直性脊柱炎骶髂关节病变的患者,MRI检查比CT检查可以诊断出更多的病灶;对于患者的骨质硬化和骨质侵蚀的诊断,CT检查的检出率明显高于MRI的检出率,两组数据比较,差异具有统计学意义(P<0.05)。结论:早期强直性脊柱炎骶髂关节病变的诊断科采用MRI检查,但对于强直性脊柱炎骶髂关节病变分级的诊断可采用CT检查。

Objective:To explore the comparison of the results of CT examination and MRI examination in sacroiliac joint lesionsof patients with ankylosing spondylitis.Methods:The sacroiliac joint lesions in 32 patients with ankylosing spondylitis wereselected.We performed statistics and classification on the clinical features of CT and MRI in all patients.Results:For sacroiliacjoint lesions in patients with grade I ankylosing spondylitis,MRI examination can diagnose more lesions than CT.For the diagnosisof bone sclerosis and bone erosion in patients,the detection rate of CT was significantly higher than that of MRI.The differencesbetween groups were statistically significant(P<0.05).Conclusion:Diagnosis of early ankylosing spondylitis can select MRI,but thediagnosis of grading of the lesion of the sacral joint in ankylosing spondylitis can select CT.
