Our goal was to assess the typical appearance of normal liver tissue immediately after
radiofrequency ablation (RF-ablation) when imaged with contrast-enhanced ultrasound, CT …

Rimlike contrast enhancement on morphologic imaging and increased tracer uptake on 18F-
FDG PET in the periphery of the necrosis can hamper differentiation of residual tumor from …

RATIONALE AND OBJECTIVES: The purpose of this study was to evaluate the utility of
magnetic resonance (MR) imaging for indicating the extent of true tissue necrosis of the liver …

The aim of this study was to assess the effect of vascular occlusion on radio-frequency (RF)
lesion size and on potential associated biliary and portal lesions. Radio-frequency lesions …

Image-guided radiofrequency (RF) ablation has been used to treat both resectable and
nonresectable hepatic tumors. A precise imaging assessment of the therapeutic response …

OBJECTIVE. The objective of this study was to compare CT and sonography for monitoring
radiofrequency (RF) lesions in porcine livers. SUBJECTS AND METHODS. RF lesions (n …

B, Unenhanced axial CT scan obtained 1 day after ablation shows low-attenuation lesion
with central high attenuation compatible with radiofrequency ablation area. Note that treated …

RATIONALE AND OBJECTIVES: A major limitation of radiofrequency (RF) ablation is its
inability to produce a large enough diameter of coagulation necrosis to encompass hepatic …

BACKGROUND: This review examines histological modifications obtained after liver
radiofrequency ablation (RFA). METHODS: A literature search has been undertaken for all …

Purpose To examine the accuracy of the unenhanced zone at contrast material–enhanced
ultrasonography (US) in predicting coagulative necrosis during and 21 days after …
