The prediction of radiofrequency ablation zone volume using vascular indices of 3-dimensional volumetric colour Doppler ultrasound in an in vitro blood-perfused bovine liver model

Abstract

Although FI was associated with ablation zone volumes, it could not sufficiently explain their variability, limiting its clinical applicability. VI, FI and VFI are not clinically useful in the prediction of RF ablation zone volume in the liver. Advances in knowledge: Despite a significant association of FI with ablation zone volumes, VI, FI and VFI cannot be used for their prediction. Different Doppler vascular indices need to be investigated for clinical use.

What is the difference in ablation zone of multi-bipolar radiofrequency ablation between liver cirrhosis and normal liver background? – a prospective clinical study

“…Residual analysis was used to assess the normality assumption. The model fit the following criterion as previous reported [23]. Statistical significance was defined as p < 0.05.…”

Identification of 2 Potential Core Genes for Influence of Gut Probiotics on Formation of Intracranial Aneurysms by Bioinformatics Analysis

“…Nobuhiro Kajihara et al found that low glucose conditions exacerbated mtROS production through activation of fatty acid oxidation in bovine aortic endothelial cells [18]. Other researchers have also used cattle as their own experimental models [19][20][21][22][23][24]. We used the GSE75240 dataset to show that gut microbes can change the expression of proteins or genes in the blood.…”

Study of flow effects on temperature‐controlled radiofrequency ablation using phantom experiments and forward simulations

“…Experimental studies of the combined impact of large vessel and background perfusion effects can be realized as retrospective evaluation of clinical treatments, 4,25 in the preclinical setting, 26 as well as by using machine‐perfused ex‐vivo liver setups 11,27‐29 . Yet, most studies so far have used impedance‐controlled RF generators.…”

“…Experimental studies of the combined impact of large vessel and background perfusion effects can be realized as retrospective evaluation of clinical treatments, 4,25 in the preclinical setting, 26 as well as by using machineperfused ex-vivo liver setups. 11,[27][28][29] Yet, most studies so far have used impedance-controlled RF generators. For example, Bitsch et al 11 observed both size reductions and Conclusion: While the temperature control mechanism did not detect the heat sink effect in the case of the smallest channel radius, it counteracted the heat sink effect in the case of the larger channel radii with an increased energy input; this explains the increase in ablated area toward high flow rates (for r = 2.3 mm).…”
