PDFAbstract
Objective To analyze the value of MR and CI in the diagnosis of hip joint lesion in ankylosing spondylitis. Methods Sixty patients with suspected hip joint lesion in ankylosing spondylitis were examined by spiral CT and MRI scanning. The application value in the diagnosis of hip joint lesion in ankylosing spondylitis was compared between the two methods. Results Among the 60 patients (120 hip joints) with AS, CT findings of hip joints of 57 cases showed abnormalities, and the positive rate was 95.0%. The main finding of CT was joint space stenosis while the findings of MR showed early stage of the hip joint space back-end stenosis, articular capsulitis, BMFD, BME and enthesis imflammation. Conclusion CT can display the fine structure of the hip joint sclerotin. However, its resolution to soft tissues is lower than that of MR. The resolution of MR to soft tissues is high and it can clearly show the joint capsule effusion, enthesis imflammation, BMFD and BME signs.
