The additional role of two-dimensional shear wave elastography (2D-SWE) in assessing lacrimal gland stiffness was also evaluated.Material and methods: This observational, cross-sectional study included 35 pSS patients and 35 age- and sex-matched healthy controls. LGUS score I incorporated four grey-scale ultrasound parameters, while LGUS score II relied solely on glandular homogeneity. Both scoring systems were evaluated for diagnostic accuracy and interobserver agreement. SWE measurements of lacrimal gland elasticity were also recorded and compared between groups.Results: LGUS score II achieved diagnostic performance comparable to LGUS score I, with areas under the curve (AUC) of 0.831 and 0.829, respectively (p=0.961). Sensitivity was higher for LGUS score II (94.29%) than for LGUS score I (85.70%), with both scores demonstrating identical specificity (68.57%). Interobserver agreement was good for LGUS score II (κ=0.707) and moderate for LGUS score I (κ=0.553). SWE measurements showed no significant differences in mean elasticity values between the pSS and control groups (8.78±2.03 kPa vs. 9.27±2.07 kPa, p=0.158).Conclusion: LGUS score II (glandular homogeneity) offers a reliable, time-efficient diagnostic approach for pSS, providing similar accuracy to the more complex LGUS score I with enhanced interobserver reliability, while the potential of 2D-SWE remains limited by methodological inconsistencies and requires further standardization.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"149-156"},"PeriodicalIF":0.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143545290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The elasticity of biological tissues can be reflected by measuring the propagation velocity of shear waves. Therefore, accurate estimation of shear wave velocity is crucial.Material and methods: In this study, we proposed a robust estimation method based on a cyclic shifting algorithm (CSA) for measuring shear wave group velocity in homogeneous media. To validate the utility of the algorithm, we conducted accuracy analysis and robustness analysis with different noise levels in the digital phantom used for the standardization of shear wave velocity by Quantitative Imaging Biomarker Alliance (QIBA) of the Radiological Society of North America.Results: The estimated shear wave velocities (SWV) of the elastic digital phantoms with Young's moduli 3 kPa, 6 kPa, 15 kPa, 30 kPa are 1.0156 m/s, 1.4065 m/s, 2.1875 m/s, 3.1250 m/s, respectively. When adding Gaussian white noise with 0 dB, the relative errors of the estimated SWVs are 2.5%, 4.8%, 11.8%, 20.5%, respectively. The estimated SWVs in the gelatin phantom with gelatin concentration of 7% and 10% are 2.0442 m/s and 3.1237 m/s. Compared with the existing two representative estimation algorithms, the estimation algorithm proposed in this paper has a higher anti-noise performance due to effective energy accumulation in the frequency domain.Conclusions: The proposed SWV method based on CSA in frequency domain is a robust shear wave group velocity estimation method, which seems to be a useful tool in homogeneous media for ultrasound elastography.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"165-174"},"PeriodicalIF":0.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142869815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
