摘　　要：目的:探讨超微血流成像(SMI)技术对膝关节滑膜血管翳微血流信号的检出效果。方法:分别用能量多普勒(PDUS)和超微血流成像(SMI)技术对41例预行全膝关节置换术的RA患者双侧膝关节髌上囊82个滑膜血流信号进行检测。并且对行全膝关节置换术的49个滑膜病理进行分级。比较PDUS与SMI对滑膜血管的显示率,分析SMI分级与病理分级之间的相关性。结果:41例患者,行全膝关节置换的膝关节49个。增厚滑膜内PDUS血流信号显示率为84.1%、SMI血流信号显示率为93.9%,χ2=3.994,(P <0.05)。PDUS与SMI滑膜血流信号分级的一致性为Kappa=0.513。SMI分级与滑膜病理分级之间具有正相关性r S=0.697,(P <0.05)。结论:SMI与PDUS相比对微血流的显示率高,SMI分级与病理分级之间具有正相关性,SMI技术对RA患者滑膜的血管翳有良好的检出效果。Objective:To investigate the effect of superb microvascularimaging(SMI)on the detection of microvascular blood flow signals in the synovial membrane of the knee joint.Methods:Forty-one patients with preoperative total knee arthroplasty were examined with power Doppler ultrasound(PDUS)and superb microvascular imaging(SMI).A total of 82 synovial membranes were detected in bilateral supracondylar sacs.At the same time,the distribution of blood vessels in 49 synovial pathological specimens of total knee arthroplasty was graded.The display rate of synovial grading between PDUS and SMI was compared,and the correlation between SMI classification and pathological grade was analyzed.Results:Among the 41 patients,49 knees undergoing total knee arthroplasty.The thickening synovial PDUS blood flow signal display rate was 84.1%,SMI blood flow signal display rate was 93.9%,χ^2=3.994,(P<0.05).The consistency of PDUS and SMI synovial blood flow signal grading was Kappa=0.513.There was a positive correlation between SMI classification and synovial pathological grade rS=0.697,(P<0.05).Conclusion:Compared with PDUS,SMI has a high detection rate of synovial flow signals.There is a positive correlation between SMI classification and pathological grade.SMI technique has a good effect on the vasospasm of synovial membrane in RA patients.
