Diagnostic value of shear wave sonoelastography in differentiation of benign from malignant thyroid nodules
European Journal of Radiology Apr 17, 2020
Aghaghazvini L, et al. - In the present study, the researchers sought to analyze the effectiveness of shear wave elastography (SWE), utilizing both qualitative and quantitative methods, alone and in conjunction with other B-mode features. One hundred seventeen patients with 123 nodules were studied both by conventional ultrasonography and SWE. One hundred twenty-three nodules in 117 individuals were assessed. Poor margins, hypoechogenicity, micro-calcification, color Doppler grades III and IV, color map grades IV and V, maximum and minimum velocity were significantly associated with malignancy. Data reported that the best cut-off point for differentiation of benign from malignant nodules was 3.63 m/s for maximum velocity and 3.44 m/s for mean velocity. Real-time SWE is a promising test for patients' preoperative malignancy risk stratification and has the strongest predictive value for both conventional and elastic variables.
