SE-085 - Intra-hepatic arterial contrast-enhanced ultrasound to evaluate the drainage area of hepatocellular carcinoma: A prospective image comparison study
Abstract
Purpose
To evaluate the value of the Intra-hepatic arterial contrast-enhanced ultrasound (IHA-CEUS) in showing blood drainage area characteristics in HCC during transarterial chemoembolization (TACE) by comparing with traditional contrast-enhanced ultrasound (CEUS).
Material and methods
59 HCC lesions in 48 Patients underwent TACE therapy were enrolled in this study. Traditional ultrasound and CEUS were performed pre-operation, then contrast-enhanced computed tomography(CECT)and IHA-CEUS were performed during TACE. The lesions which its corona enhancement can’t be detected by CECT is excluded. Visualization rate of the corona enhancement in CEUS and IHA-CEUS imaging modalities in different diameter of HCC was recorded and compared. The correlation between the thickness of the corona enhancement and the diameter of the lesion was also analyzed.
Results
The visualization rate of the drainage area in IHA-CEUS was 83.3% (45/54), respectively, 22.2% (12/54) for traditional CEUS (P<0.001). Comparing with the traditional CEUS, the visible rate in IHA-CEUS of the drainage area in HCC less than 3cm, 3-5cm and more than 5cm lesions was 78.1% (25/32) vs 15.6% (5/32), 91.7% (11/12) vs 41.7% (5/12) and 90.9% (10/11) vs 27.3% (3/11), respectively, with statistically significant differences (P < 0.001, P=0.031, P=0.016). The positive linear correlation between tumor size and drainage area thickness in IHA-CEUS(R2=0.27, P<0.001) is better than that in CEUS (R2=0.07, P=0.043).
Conclusion
Comparing with conventional CEUS, IHA-CEUS can improve the visualization rate effectively to display the drainage area of HCC lesions, which may become a novel way to evaluate the drainage area of HCC.
