Transarterial Chemoembolization with Drug-eluting Beads in Hepatocellular Carcinoma: Usefulness of Contrast Saturation Features on Cone-Beam Computed Tomography Imaging for Predicting Short-term Tumor Response

Marginal contrast saturation showed a high positive predictive value for short-term tumor response. This technique may improve the success rates of DEB transarterial chemoembolization procedures and may reduce technical difficulties and shorten procedural time.
