目的:探讨CT和MRI检查在诊断骶髂关节病变中的临床价值。方法:选取我院2015年2月-2016年2月79例强直性脊柱炎骶髂关节病变患者,均经CT、MRI检查,观察两种检查的诊断结果。结果:CT、MRI对骶髂关节病变的0、Ⅰ级检出率结果对比差异显著(P<0.05);CT对骨质硬化、骨质侵蚀检出率均高于MRI(P<0.05)。结论:MRI检查方法敏感性高,无放射性,CT检查骶骼关节病变具有更高的空间分辨率,对于骨质硬化、侵蚀等早期症状检出率较高。
Objective: To investigate the clinical value of CT and MRI in the diagnosis of sacroiliac joint disease. Methods: 79 patients with sacroiliac joint disease of ankylosing spondylitis in our hospital from February 2015 to February 2016 were examined by CT and MRI, and the diagnostic results of the two examinations were observed. Results: The detection rates of CT and MRI in grade 0 and grade Ⅰ of sacroiliac joint were significantly different (P <0.05). The detection rate of osteopetrosis and bone erosion in CT was higher than that in MRI (P <0.05). Conclusion: The MRI examination method is sensitive and non-radioactive. CT examination of sacroiliac joint lesions has higher spatial resolution and higher detection rate of early symptoms such as sclerosis and erosion.
