Abstract

Objective To explore the application value of CT and MRI in the diagnosis of ankylosing spondylitis sacroiliac joint lesions. Methods Eighty cases of ankylosing spondylitis patients were randomly selected as the research object from October 2014 to October 2014, and all of them had successively CT and MRI examination, to observe and analyze the two inspection ways for this disease. Results The detection rate of MRI for sacroiliac joint lesionsⅠ, Ⅱ of ankylosing spondylitis were significantly higher than that of CT (P<0.05). The detection rate of MRI for ankylosing spondylitis sacroiliac joint lesions under the joint surface erosion, surface joints bone cystic change, waist 5 s1 joints lesions, soft tissue swelling were significantly higher than that of CT (P<0.05), but the detection rate of the two methods in checking hyperplasia of the articular surface hardening, broadening or narrowing, joint stiffness under the joint had not significant difference (P>0.05). Conclusion The detection rate of MRI in the diagnosis of ankylosing spondylitis sacroiliac joint lesions is higher than CT, which has good application value and is worthy of clinical popularization and application.
