Article Synopsis
- The study aimed to explore computed tomography-based thermography (CTT) for predicting ablation zones during microwave ablation (MWA) in a porcine liver model.
- CTT effectively visualized ablation zones, showing a significant correlation between CT attenuation values and temperature changes, implying that the technique can be used to accurately assess treatment areas.
- The findings suggest that CTT could be beneficial in clinical settings to improve patient outcomes and potentially reduce the risk of local cancer recurrence.
Article Synopsis
- Computed tomography-based Thermography (CTT) is being explored as a non-invasive way to monitor temperature during ablation procedures, but it faces challenges from inter-scan motion artifacts that require registration.
- The study analyzed different registration algorithms to minimize these artifacts during microwave ablation of liver tissue in a porcine model, using feedback from 15 radiologists to assess effectiveness.
- Results indicated that combined registration methods were more effective at reducing ablation probe movement compared to using a single registration method, highlighting the importance of proper registration in these procedures.
The aim of this study was a three-dimensional analysis of vascular cooling effects on microwave ablation (MWA) in an ex vivo porcine model. A glass tube, placed in parallel to the microwave antenna at distances of 2.5, 5.

- The study investigated how nearby blood vessels impact the effectiveness of microwave ablation (MWA) in liver tissue, using ex vivo experiments on pig liver.
- Significant cooling effects were noted when vessels were close to the MWA antenna (5-10 mm), particularly with vessels of 3 mm or larger that had blood flow rates of 1 mL/min or more.
- The findings suggest that while nearby vessels can cool the area during ablation, the proximity of the antenna to the vessel is the most critical factor, and treatment plans should account for these cooling effects.
Multibipolar radiofrequency ablation (RFA) is an advanced ablation technique for early stage hepatocellular carcinoma and liver metastases. Vessel cooling in multibipolar RFA has not been systematically investigated. The objective of this study was to evaluate the presence of perivascular vital cells within the ablation zone after multibipolar RFA.
