Comparison of volume perfusion computed tomography (VPCT) and contrast-enhanced ultrasound (CEUS) for assessment of therapeutic effect of transarterial chemoembolisation (TACE)

Zielsetzung: To compare contrast-enhanced ultrasound (CEUS) and volume perfusion computed tomography (VPCT) for response evaluation of hepatocellular carcinoma (HCC) to transarterial chemoembolisation (TACE). Material und Methodik: Twenty consecutive patients with inoperable HCC underwent CEUS and VPCT in the pre- and post-TACE setting (mean, 1 day). Quality of CEUS and VPCT was rated as good/adequate/poor. Good and adequate were rated as diagnostic. We measured hepatic perfusion index (HPI), arterial liver perfusion (ALP), blood flow (BF) and blood volume (BV) at both time points by VPCT, calculated ratios and…
