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.
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.
我们研究的目的是调查猪肺射频消融术后消融灶的时间进程变化以及CT与组织病理学结果之间的相关性。
CT上的磨玻璃样衰减导致对坏死灶大小的高估。CT上的分层结构表现与组织病理学结果一致。虽然CT表现反映了组织病理学结果,但在CT图像的临床解读中应注意消融灶与高密度区域的分离。
