| 目的 探讨彩色多普勒超声(CDUS)对早期中轴型脊柱关节病(axSpA)患者骶髂关节炎的诊断价值。方法 收集本院早期axSpA患者,结合骶髂关节MRI分为活动组19例和非活动组25例,收集同期志愿者30名作为正常对照组。观察并比较3组骶髂关节的血流显示率、血流丰富程度及血流阻力指数(RI)。采用Kappa 分析比较超声与MRI诊断的一致性。结果 活动组(31个关节)骶髂关节血流显示率(28/31,90.32%)高于非活动组(50个关节,26/50,52.00%)及正常对照组(60个关节,33/60,55.00%;χ2=12.65、11.54,P<0.01);非活动组与正常对照组间差异无统计学意义(χ2=0.10,P=0.74)。3组间血流丰富程度差异无统计学意义(P=0.78)。活动组RI(0.57±0.07)低于非活动组(0.70±0.09)及正常对照组(0.78±0.11;t=0.14、0.16,P<0.01);非活动组与正常对照组的RI差异无统计学意义(P=0.71)。以RI=0.64诊断活动性骶髂关节炎,与MRI相比Kappa=0.64。结论 CDUS可显示骶髂关节异常血流,对诊断axSpA活动性骶髂关节炎有一定价值。 |

| Objective To investigate the diagnostic value of color Doppler ultrasound (CDUS) in sacroiliitis in patients with early axial spondyloarthropathy (axSpA). Methods According the results of MRI, early axSpA patients were devided into active group (n=19) and inactive group (n=25); 30 cases of asymptomatic volunteers were included as a control group. Sacroiliac joint of the three groups were tested by CDUS, the color flow signs and blood flow resistance index (RI) were compared. Consistance of RI in diagnosis sacroiliitis were compared with MRI by Kappa test. Results Blood flow demonstration rate in active group (31 joints, 28/31, 90.32%) was significantly higher than that of the inactive group (50 joints, 26/50, 52.00%) and control group (60 joints, 33/60, 55.00%; χ2=12.65, 11.54, P<0.01), which had no significant difference between inactive group and control group (χ2=0.10, P= 0.74). The indegree of blood flow was not statistically different among three groups (P=0.78). RI in active group (0.57±0.07) was lower than that of in inactive group (0.70±0.09) and control group (0.78±0.11; t=0.14, 0.16, P<0.01). There was no significant difference of RI between inactive and control group (P=0.71). Taking RI=0.64 for diagnosis of active sacroiliitis, the Kappa value was 0.64 compared with MRI. Conclusion The abnormal flow at sacroiliac joint can be detected by CDUS which have a certain value in diagnosis of early axSpA. |
