| 目的 分析强直性脊柱炎活动期MRI与CT的影像表现，及影像学检查对临床治疗的指导意义。 方法 回顾性分析2015年6月至2018年12月经我院风湿科确诊的48例AS脊柱受累患者的资料，48例患者均临床确诊AS多年，近期腰部疼痛加重，所有患者在出现症状后2周之内进行MRI及CT检查，通过其影像表现及检查方法的对比观察，对强直性脊柱炎病情活动期进行评价。结果 48例AS患者,39例男性，9例女性，年龄在24~53岁之间，MRI检查中胸椎11例，腰椎39例，其中18例患者显示椎体终板前上、后上角T1WI低信号，T2WI及压脂高信号改变，30例显示整个及部分椎体T1WI低信号，T2WI及压脂高信号，11例椎间盘T2WI显示髓核结构不均一，信号减低，椎间盘高度降低，21例椎小关节局部骨质及周围滑膜T1WI低信号，T2WI及压脂高信号；CT检查中28例椎体边缘骨质增生，25例椎体呈“方椎”，8例脊柱呈“竹节椎”，21例椎小关节炎，其中5例椎小关节骨性连接，11例椎间隙变窄，密度增高。结论 强直性脊柱炎活动期的MRI及CT检查都具有一定的特点，但MRI检查对AS活动期显示更具特征性，因此应优选MRI检查。 |

| [Abstract] Objective To investigate the MRI and CT features of AS in active stage,and guiding signiflcance of imaging examination in clinical treatment.Methods rRetrospective analysis of 48 AS patients with spinal disease in the department of rheumatology of our hospital from June 2015 to December 2018 is conducted. All patients was diagnosed as AS for many years with worsening of lumbar pain recently. All patients were performed with MRI and CT within two weeks after symptoms .To evaluate active ankylosing spondylitis, comparative observation of MRI and CT examination methods was made for all patients within two weeks. Results?Among the 48 AS patients, 39 were male and 9 were female, aged between 24 and 53 years old.MRI examination of?thoracic vertebra11 cases ,lumbar vertebra?39 cases ,18 patients showed T1WI?low signal,?T2WI and pressure?fat high?signal changes?in the anterior and posterior upper corners of vertebral body, T1WI showed?low?signal,T2WI and pressure?fat showed?high?signal changes?of?the entire and partial vertebral bodies?in 30 cases,Disc?in 11 cases showed T2WI?uneven nucleus pulposus structure, decreased signal and decreased disc height.Low signal, T1WI showed low signal ,T2WI and pressure fat?showed high?signal of local bone and peripheral synovium in 21 cases of facet joints.CT examination of 28 cases with vertebral margin bone hyperplasia ,In 25 cases, the vertebral body was "square vertebra ", in 8 cases, the spinal column was" bamboo", and in 21 cases, the vertebral small arthritis,Among them ,5 cases had Bone junction of vertebral facet joint ,11 cases had narrow vertebral space, density increased.Conclusion The MRI and CT examination in the active stage of ankylosing spondylitis have some characteristics, but the MRI examination is more characteristic for the active stage of AS, so the MRI examination should be selected. |
