Abstract:
Objective:To investigate the study on the diagnostic value of multimodal ultrasound technique for the lesion of extensor carpi ulnaris(ECU)tendon in patients with rheumatoid arthritis(RA).Methods:A total of 175 RA patients who were confirmed by the department of rheumatology of Yantaishan Hospital of Yantai city from December 2021 to January 2023 were selected,and them were included into the RA group.Other 50 patients without RA but with clinical symptoms of wrist were included into the non-RA group,and 50 healthy volunteers were included into the healthy control group.All subjects underwent routine ultrasound and shear wave elastography(SWE)examination on wrist,and then,the characteristics of ultrasound images of wrists and the blood flow distribution of ECU power Doppler ultrasonography(PDUS)were recorded.SWE was used to measure ECU to obtain elastic modulus index(EI)and velocity modulus index(VI).The differences between three groups were compared,and the receiver operating characteristic(ROC)value of RA patients were drawn,so as to confirm the area under curve(AUC)value and optimize cutoff value.Results:There were significant differences in EI and VI of the ECU tendon among three groups(F=61.15,61.28,P<0.05),respectively.The optimal cut-off values of EI and VI were respectively 319.35 kPa and 10.55 m/s in RA patients.In RA patients,age and disease course had significant influences on EI(r=0.19,0.21,P<0.05),and age,disease course,ultrasound score of wrist joint,and grade of power Doppler ultrasonography PDUS of the ECU tendon(ECUPDUS)had significant influences on VI(r=0.19,0.15,-0.16,-0.17,P<0.05).Conclusion:SWE is able to quantitatively and non-invasively assess the stiffness information of the ECU tendon in RA patients.After the supplement of gray-scale ultrasound and PDUS,multimodal ultrasound technique can clearly judge the correlation of the lesions of ECU tendon of RA patients.
