Abstract:
Objective:To investigate the clinical value of magnetic resonance imaging (MRI) in the early diagnosis of ankylosing spondylitis involving hip joint.Methods:One hundred and twenty-eight patients with ankylosing spondylitis involved in the hip joint were selected who were treated in the People′s Hospital of Longhua District from January 2017 to February 2020. The patients were divided into computed tomography(CT) group (64 cases) and MRI group (64 cases) according to the examination method of CT and MRI were performed respectively, and the incidence of abnormal hip joints were analyzed, and the prognostic treatment effects of the two groups were compared after following up.Results:Twenty-seven cases of fat deposition, 43 cases of subchondral bone marrow edema and 31 cases of inflammatory changes of tendon and ligament attachment were detected in MRI group, while CT didn′t showed these changes. Thirty-four cases of hip joint lesions were detected in CT group, the detection rate was 53.1%(34/64), and 56 cases of hip joint lesions were detected in MRI group, the detection rate was 87.50(56/64), the difference was statistically significant ( P<0.05). After treated for 3 months, the cure rate of the MRI group was higher than that of the CT group: 65.6%(42/64) vs. 34.4% (22/64), the difference was statistically significant ( χ2=18.11, P<0.05). Conclusions:MRI is an important imaging method for the early diagnosis of ankylosing spondylitis involving the hip joint, and its diagnostic sensitivity is better than that of CT.
