To assess intra and inter-rater reliability of available radiological scoring methods in ankylosing spondylitis (AS).
Two trained raters evaluated 44 complete sets of AS radiographs. The cervical and lumbar spine was graded from zero to 4 according to the Bath Ankylosing Spondylitis Radiology Index (BASRI). Hip joints were graded according to the BASRI-hip method. Sacroiliac (SI) joints were scored according to the New York method (0-4). The anterior and posterior sites of the lumbar spine were scored according to the Stoke Ankylosing Spondylitis Spinal Score (SASSS) method (0-72). Modified-SASSS was assessed by using the anterior sites of both the cervical and lumbar spine (0-72).
Both intra and inter-rater reliability were almost perfect for all the methods and intra-class correlation coefficient (ICC) for all the methods was relatively similar to each other. The BASRI-spine and BASRI-total showed intra and inter-rater ICC between 0.78 and 0.98. Both SASSS and modified--SASSS reached perfect intra and inter-rater reliability with ICC between 0.86 and 0.99. The ICC of the BASRI-hip was substantial to perfect, ranging from 0.77 to 0.88. Time spent to score a set of radiographs using the BASRI-spine was <45 seconds, whereas >60 seconds for both SASSS and mSASSS methods.
After training, all of these methods have demonstrated almost perfect intra and inter-rater reliability. The BASRI was easier to perform and less time consuming than SASSS methods.
评估强直性脊柱炎（AS）现有放射学评分方法的评分者内和评分者间信度。
两名经过培训的评分者对44套完整的AS X光片进行评估。根据巴斯强直性脊柱炎放射学指数（BASRI），颈椎和腰椎从零到4级进行分级。髋关节根据BASRI-髋关节方法进行分级。骶髂（SI）关节根据纽约方法进行评分（0-4级）。腰椎的前后部位根据斯托克强直性脊柱炎脊柱评分（SASSS）方法进行评分（0-72分）。改良SASSS通过使用颈椎和腰椎的前部进行评估（0-72分）。
所有方法的评分者内和评分者间信度几乎都很高，所有方法的组内相关系数（ICC）彼此相对相似。BASRI-脊柱和BASRI-总分的评分者内和评分者间ICC在0.78至0.98之间。SASSS和改良SASSS均达到了完美的评分者内和评分者间信度，ICC在0.86至0.99之间。BASRI-髋关节的ICC从高到完美，范围为0.77至0.88。使用BASRI-脊柱对一组X光片进行评分的时间<45秒，而SASSS和mSASSS方法均>60秒。
经过培训后，所有这些方法都显示出几乎完美的评分者内和评分者间信度。BASRI比SASSS方法更易于操作且耗时更少。
