【摘要】:目的探讨利用DWI ADC值对AS患者骶髂关节炎症活动进行量化评价的可行性。方法将22例AS患者根据AS病情活动指数(BASDAI)评分分为静止组(4分,n=8)及活动组(≥4分,n=14)。另选18名健康志愿者作为正常对照组。对3组均行骶髂关节MR检查,获得各组骶髂关节骨性关节面下及L5椎体骨髓的ADC值(ADCSIJ值、ADCL5值)及骶髂关节的相对ADC值(rADCSIJ值)。对静止组及活动组于MR检查前行C反应蛋白(CRP)及血沉(ESR)检查,并进行统计学分析。结果静止组与正常对照组间ADCSIJ值、rADCSIJ值差异均无统计学意义(P均0.05)。活动组与静止组及正常对照组间ADCSIJ值、rADCSIJ值差异均有统计学意义(P均0.05)。3组间ADCL5值差异均无统计学意义。AS患者ADCSIJ值、rADCSIJ值与临床BASDAI评分、ESR及CRP均呈正相关(P均0.05)。结论 DWI ADC值有助于临床辅助诊断活动期AS并判断骶髂关节炎症活动程度。
