Abstract: Objective The aim of this study was to evaluate the value of contrast ultrasonography (CEUS) and virtual touch tissue quantification (VTQ) in differentiating hepatic hemangioma from hepatocellular carcinoma (HCC). Methods 93 patients with intrahepatic space-occupying lesions were encountered in our hospital between April 2018 and April 2021, and all underwent CEUS and VTQ check-up. The CEUS parameters including start enhancement time, peak enhancement time and peak intensity, and the shear wave velocity (SWV) of intrahepatic foci, surrounding tissues and SWV ratio of foci/surrounding tissue obtained by VTQ were recorded. Thediagnostic efficacy was determined by ROC analysis. Results Out of our series, the hepatic hemangioma was found in 40 cases, and HCC in 53 cases based on CT/MRI scan or post-operational histopathological examination; the onset enhancement time and peak enhancement time in patients with HCC were (8.2±1.2) s and (16.7±3.3) s, significantly shorter than [(15.9±5.0) s and (45.7±15.4) s, respectively, P < 0.05] in patients with hepatic hemangioma; the SWV of hepatic foci, the SWV of surrounding tissues and SWV ratio in patients with HCC were (2.7±0.9), (2.0±0.8) and (1.8±0.7), significantly greater than [(1.5±0.4), (1.4±0.6) and (1.1±0.3), respectively, P<0.05] in patients with hepatic hemangioma; the ROC analysis showed that the onset enhancement time, peak enhancement time, the SWV of hepatic foci, the SWV of surrounding tissues and SWV ratio all had some diagnostic efficacy with the AUC of 0.754, 0.818, 0.758, 0.802 and 0.809, respectively; we set the onset enhancement time ≤12.080 s, the peak enhancement time≤26.530 s, the SWV of hepatic foci≥2.015 m/s, the SWV of surrounding tissues ≥1.920 m/s and SWV ratio ≥1.280 as the optimal cut-off-value, the HCC was diagnosed in 48 cases when any one of the five parameter meeting, with sensitivity of 0.906, specificity of 0.950, accuracy of 0.925, positive predictive value of 0.960 and negative predictive value of 0.884. Conclusion There are significant differences in CEUS and VTQ results between HCC and hepatic hemangioma, by which the clinicians could make differentiation of benign and malignant intrahepatic lesions.
