Abstract:
Objective:To explore the effects of ablation of normal rabbit liver tissue by combination of high intensity focused ultrasound(HIFU) and iodized oil emulsion(HIFU liposome 2,HL-2) and the grey scale changes in target region.Methods:Rabbit liver was ablated with HIFU under certain parameters one hour after HL-2 was injected intravenously in the experimental group.The grey scale in target region and the exposure time were recorded.All processes in control group were the same as those in the experimental group only HL-2 was replaced by saline.Results:The changes of grey scale in the target region were similar in two groups.Typical coagulation necrosis happened both in two groups under gross and histological examination.The energy efficiency factor (EEF)in the experimental group was less than that in the control group(P
