Abstract
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). 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. Seventy HCC tumors with sizes of P < 0.001). Dual phase CBCT is significantly more sensitive than hepatic angiography, contrast enhanced CT, and MRI in detecting smaller than 3 cm HCC tumors and can be a helpful modality in making accurate planning for treatment of HCC.
