摘要

PURPOSE. Use of sonoelastography to diagnose De Quervain's disease may increase diagnostic accuracy and provide a quantitative index for disease severity. We aimed to apply sonoelastography to detect changes in the physical properties of target tendons. MATERIALS AND METHODS. This is a prospective comparative study conducted between January and March 2018. All patients were diagnosed by physical examination and then underwent gray-scale sonography, Doppler sonography, and ultrasound elastography over bilateral wrists. Abnormal findings and the elasticity of affected tendons were compared with those of the asymptomatic side. RESULTS. In total, 24 patients ranging in age from 26 to 74 (mean = 43.67 ± 15.45) years were enrolled in the study. There was a significantly higher rate of effusion and intratendinous hypoechoic lesions for affected tendons. The strain ratio of tendons was also significantly lower for the De Quervain's disease group as compared with asymptomatic group (0.80 ± 0.52 vs. 1.73 ± 0.50, p ＜ 0.001). CONCLUSION. Sonoelastography can help diagnose De Quervain's disease as an inexpensive, rapid, and clinic-based tool.
