Objective: The objective of our study was to investigate the time course changes of the ablated lesion after radiofrequency ablation in the porcine lung and the correlation between CT and histopathologic findings.
Conclusion: Ground-glass attenuation on CT led to overestimation of the size of necrotic lesions. The layered structural findings on CT were consistent with the histopathologic findings. Although CT findings reflect the histopathologic findings, attention should be paid to the dissociation of ablated lesions and high-density areas in clinical interpretation of CT images.
