Monitoring after radiofrequency ablation of liver tumors: contrast-enhanced ultrasound vs. contrast-enhanced computer tomography, two days after procedure

Abstract

The quality of tumor residue detection in 48-h CEUS was comparable to that of 48-h CECT. This finding suggests the CEUS being a feasible substitute for CECT. Both methods show reasonable sensitivity; therefore this timing seems to be appropriate for the first post-treatment control while also allowing for early retreatment if residual tumor tissue is found.

Prognostic value of enhancement rate by enhanced ultrasound in hepatitis B virus‐positive hepatocellular carcinoma undergoing radiofrequency ablation

“…Therefore, pretreatment accurate quantification assessment of tumor perfusion may be significance for predicating therapeutic outcome of the RFA. In previous studies, the characteristic of blood perfusion in HCC and post‐ablation effect were mainly assessed though conventional enhanced imaging examination, which may obtain inaccurate results due to subjective factors and unable to directly reflect the hemodynamic status . So, assessment of blood perfusion in HCC before RFA characterized by highly reproducible, technically feasible and pathologist independent is required.…”
