Abstract：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%,χ2=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.
