Abstract:
Objective To investigate the imaging manifestations of inflammatory bowel disease-associated spondyloarthritis(IBD-SpA).Methods A retrospective analysis was conducted on 85 patients with inflammatory bowel disease(IBD)who underwent abdominal CT and MRI examinations.Patients with pregnancy,lactation,psoriasis,tumors,and other conditions were excluded through medical record screening,all patients met the diagnostic criteria for IBD.The presence of spondyloarthritis(SpA)was confirmed through ima-ging findings,and the imaging characteristics of the location and bone changes of SpA were observed.Twenty patients who under-went abdominal CT examination during the same period were selected as the control group.Results A total of 85 patients with IBD under-went CT and MRI examinations,the detection rate of MRI(37.6％)was significantly higher than that of CT(30.6％)(P＜0.05).Based on comprehensive imaging features,5 cases of grade 1,13 cases of grade 11,11 cases of grade Ⅲ,and 3 cases of grade Ⅳ,IBD-SpA were diagnosed.In the control group,1 case of sacroiliitis was detected,of which 1 case of grade Ⅱ.The detection rate of CT in the IBD group(30.6％)was significantly higher than that in the control group(5％)(P＜0.05).Conclusion The incidence of SpA is relatively high in patients with IBD.Both CT and MRI have certain diagnostic value for IBD-SpA.CT has diagnostic advantages in bone sclerosis and joint space narrowing,while MRI can better reflect minor lesions and early bone marrow edema changes.The com-bination of CT and MRI examinations can provide diagnostic evidence for clinicians and effectively improve patient symptoms.
