The Diagnostic Value of Real-time Shear Wave Ultrasound Elastography in the Differentiation of Hepatic Hemangioma and Hepatocellular Carcinoma

Abstract

Objective: To explore the diagnostic value of real-time shear wave elastography (SWE) in hepatic hemangioma (ANGI) and hepatocellular carcinoma (HCC). Methods: A total of 88 patients diagnosed with angiosarcoma (ANGI) or hepatocellular carcinoma (HCC) in our department from February 2019 to February 2020 were included in this study. These patients were assigned to two groups based on pathological diagnosis: the ANGI group (n = 42) and the HCC group (n = 46). All patients underwent SWE examination, and the clinical efficacy was analyzed by comparing the average value of Young's modulus of the two groups and plotting the receiver operator characteristic (ROC) curve. Results: There was no significant difference in lesion diameter between ANGI and HCC patients (P > 0.05). The ANGI group exhibited a significantly higher average Young's modulus for both the lesions and the adjacent liver tissues compared to the HCC group (P < 0.001); The area under the curve (AUC) of the average value of Young’s modulus of the lesion to ANGI and HCC was 0.875 (95% CI = 0.795-0.955). Conclusion: SWE demonstrates high diagnostic accuracy in distinguishing ANGI from HCC, providing valuable clinical evidence for differentiating between the two diseases.
