Real-time shear wave elastography in differential diagnosis of hepatic alveolar echinococcosis and hepatocellular carcinoma / 中国医学影像技术

ABSTRACT

Objective: To explore the value of real-time shear wave elastography (SWE) in differential diagnosis of hepatic alveolar echinococcosis (HAE) and hepatocellular carcinoma (HCC). Methods: Twenty patients of HAE (HAE group) and 30 patients of HCC (HCC group) were enrolled. All SWE was performed before surgical operation, and the mean elasticity of Young's modulus was obtained. Taken pathological outcomes as the gold standards, the accuracy and efficacy of SWE in differential diagnosis of HAE and HCC were evaluated. Results: The mean elasticity of Young's modulus of the lesions was (34.57±10.76)kPa in HAE group, higher than in HCC group ([21.82±3.51] kPa, P<0.001). ROC curve showed that the critical point of the mean elasticity of Young's modulus of HAE and HCC was 27.43 kPa, the sensitivity was 80.00%, specificity was 97.00%, and AUC was 0.869. Conclusion: SWE has an important value in differential diagnosis of HAE and HCC.
