1
This study evaluated the correlation between spectral CT quantitative parameters and complete ablation after radiofrequency ablation for liver tumors.
-
2
109 patients who underwent RFA were analyzed, with 81 achieving complete ablation and 28 experiencing incomplete ablation based on postoperative MRI.
-
3
Significantly lower arterial phase NIC, λ-HU, and Z-eff values were found in the complete ablation group compared to the incomplete ablation group.
-
4
Logistic regression identified maximum tumor diameter, preoperative AFP levels, and vessel adjacency as independent predictive factors for complete ablation.
-
5
A combined predictive model using these factors achieved an AUC of 0.933, indicating superior predictive performance for complete ablation.
