Does Contrast-enhanced ultrasound provide better assessment of microwave ablations in a perfused porcine liver model ?

Background and aims: Microwave ablation (MWA) under different imaging gu idance is a new technique for treating liver malignancies. In this study, we wanted to fi nd out whether the use of contrast-enhanced ultrasound (CEUS) would provide better assessment o f the ablation zone in an ex vivo perfused porcine liver model. Study design: Original research Place and duration of study: Departments of Hepatob iliary and Pancreatic surgery, department of Radiology and department of Histopath ology; University hospitals of Leicester, UK.
