Objective: The objective of this study was to evaluate the sensitivity of dual phase cone-beam computed tomography (CBCT) in detecting small (<3 cm in diameter) hepatocellular carcinoma (HCC) tumors during transarterial chemoembolization (TACE). Materials and Methods: Twenty-two consecutive patients with unresectable small HCCs in whom TACE was performed were retrospectively evaluated. Contrast CT or contrast magnetic resonance imaging (MRI) was performed in all patients within 1 month prior to the procedure. Dual phase CBCT was performed prior to TACE and lipiodol-CBCT was performed after treatment. The sensitivity of dual phase CBCT in detecting small HCCs was compared to hepatic angiography, contrast enhanced CT and MRI. Results: Seventy HCC tumors with sizes of
