摘要
目的 探讨微血管血流(microvascular flow,MV-Flow)成像技术评估小关节亚临床滑膜炎的应用价值。方法对28例小关节痛患者的79个关节行超声检查,应用MV-Flow成像技术及彩色多普勒血流成像(colour Doppler flow imaging,CDFI)技术检测增厚滑膜血流状况,并分别对血流信号行半定量评分。比较增厚滑膜MV-Flow及CDFI血流显示差异以及微小血管分级的差异。结果 MV-Flow及CDFI对79个关节的血流信号检出率分别为88.6%、53.2%,MV-Flow成像技术检测关节滑膜血流显示率高于CDFI,差异有统计学意义(χ^(2)=31.030,P<0.001)。MV-Flow与CDFI对滑膜血流分级的结果未见一致性(Kappa=0.052,P>0.05)。结论 MV-Flow成像技术能更敏感地反映小关节滑膜的微血管分布及血流分级情况,可成为评价小关节炎的有效手段。
Objective To evaluate the applicability of microvascular flow(MV-Flow)imaging in evaluating low-grade inflammation of facet joints.Methods A total of 28 patients with joint pain underwent ultrasound examination,during which the blood flow in the thickened synovia was assessed using both MV-Flow imaging technology and color Doppler flow imaging(CDFI)technology.Semi-quantitative scoring was performed for blood flow signals.Differences between MV-Flow and CDFI in displaying blood flow and in vascular grading were studied.Results In a cohort of 28 patients,a total of 79 joints met the established criteria for inclusion.The detection rates for blood flow signals using MV-Flow and CDFI were determined to be 88.6%and 53.2%,respectively.MV-Flow imaging exhibited superiority in detecting synovial blood flow within the joints over CDFI,with statistically significant difference(χ^(2)=31.030,P<0.001).Furthermore,there was no consistency in grading outcomes of synovial blood flow between MV-Flow and CDFI(Kappa=0.052,P>0.05).Conclusion The MV-Flow imaging technique can more sensitively reflect the microvascular distribution and blood flow grading of facet joints,so it can become an effective means for evaluating small joint arthritis.
