骶髂关节融合断层显像(SPECT/CT)在强直性脊柱炎骶髂关节病变分期中的价值及临床观察

The value and clinical observation of the fusion tomography( SPECT/CT) in the staging of the lesions in the patients with ankylosing spondylitis

目的探讨骶髂关节融合断层显像(SPECT/CT)在强直性脊柱炎骶髂关节病变分期中的价值。方法比较67例强直性脊柱炎患者SPECT/CT与同期MR骶髂关节图像,分别进行图像判读、分期、临床符合度分析。结果SPECT/CT分级如下:0级:1例,1级:8例,2级:26例,3级:21例,4级:11例。MR分级如下:0级:3例,1级:5例,2级:23例,3级:25例,4级:11例。结论两种不同影像方法对患者分期无明显差异,SPECT/CT的骨代谢活跃情况更患者符合临床症状,有利于临床进行诊疗监测。

Objective To investigate the value of the fusion tomography（ SPECT/CT） in the staging of the lesions in the patients with ankylosing spondylitis. Methods The SPECT/CT data of 67 patients with ankylosing spondylitis were compared with MR images of those patients at the same period,and then,the image interpretation,staging,clinical compliance were analyzed,respectively. Results PECT/CT classification was as follows,i. e.,Grade 0 included 1 case,grade 1 included 8 cases,grade 2 included 26 cases,grade3 included 21 cases,and grade 4 included 11 cases. MR classification was as follows,i. e.,Grade 0 consisted of 3 cases,grade 1 of 5 cases,grade 2 of 23 cases,grade 3 of 25 cases,and grade 4 of 11 cases. Conclusion There were no significant differences between the two different imaging methods in patients with SPECT/CT. The bone metabolism of the patients with active bone metabolism was more consistent with the clinical symptoms,which is helpful for clinical diagnosis and treatment.
