Abstract
Background: Transcatheter arterial chemoembolization is one of the effective therapeutic options for hepatocellular carcinoma (HCC). Ultraselective chemoembolization is an alternative approach to improve local control, and is associated with a reduced incidence of adverse effects.
Objective: The objective of this study is to evaluate the sensitivity of cone beam computed tomography (CBCT) in detecting hepatocellular carcinoma (HCC) tumors and their feeding vessels during transarterial chemoembolization (TACE).
Materials and Methods: All patients were suspected of having or confirmed to have HCC on the basis of clinical history, underlying liver disease and/or viral infection, the diagnosis of HCC was made by imaging findings. Between January 2016 and January 2018, the prototype chemoembolization guidance software for syngo Dyna CT was retrospectively used in 20 consecutive patients with HCC tumor.
Results: The detectability of the tumor with DSA obtained at the common, proper, right, or left hepatic artery ( ie, nonselective DSA)and cone-beam CT was compared. Tumor stain and feeding branches were evaluated.The detectability of the tumor-feeding branch with non selective DSA and Dyna CT analyzing the first CT HA images was compared.
Conclusion: Tumor detectability on cone-beam CT was significantly greater than on non selective.Cone beam HA could depict (95.6%) of tumors.Nonselective DSA could depict only (72.1%). Cone-beam CT has satisfactory ability to detect tumors; could identify 81% of tumor-feeding branches at the level of the sub- sub segmental artery of the hepatic artery in HCC lesions.We believe the technical success rates of ultraselective transcatheter arterial chemoembolization may be improved by chemoembolization guidance software that uses cone-beam CT technology.
