Abstract

OBJECTIVE:: We aimed to compare the diagnostic utility of T1-weighted (T1w) and STIR MRI sequences in early spondyloarthritis (SpA) using a standardized approach to the evaluation of sacroiliac joints (SIJ) and to test whether systematic calibration of readers directed at recognition of abnormalities on T1w MRI would enhance diagnostic utility. METHODS:: Six readers independently assessed T1w and STIR MRI scans of the SIJ from 187 subjects: 75 AS and 27 preradiographic IBP patients; 26 mechanical back pain and 59 healthy volunteer controls aged

骶髂关节结构病变的评估提高了MRI对早期脊椎关节炎的诊断价值

目的:我们旨在比较t1加权(T1w)和STIR MRI序列对早期脊椎关节炎(SpA)的诊断效用，采用一种标准化的方法来评估骶髂关节(SIJ)，并测试针对T1w MRI异常识别的阅读器的系统校准是否会提高诊断效用。方法:6名读者独立评估187名受试者的SIJ T1w和STIR MRI扫描结果:75名AS和27名放射前IBP患者;26例机械性背痛患者和59例年龄
