2026-09-03 Data for: Dynamic contrast-enhanced MRI differentiates the necrotic core, injured margin, and normal lung tissue early after pulmonary cryoablation: a histopathologically validated porcine study doi:10.57760/sciencedb.46373 en This dataset contains the raw and analysed data supporting the manuscript "Dynamic contrast-enhanced MRI differentiates the necrotic core, injured margin, and normal lung tissue early after pulmonary cryoablation: a histopathologically validated porcine study". It includes: (1) measurement data for Tables 1 and 2 (CT values and DCE-MRI quantitative parameters, n = 12 Bama miniature pigs); (2) supplementary data for Tables S1-S4 (ablation zone sizes on CT/DCE-MRI and gross histology specimens, and volume correlations; sensitivity analysis of DCE-MRI parameters among different regions); (3) GraphPad Prism source files (pzfx) for statistical analyses; (4) post-processing images corresponding to Figures 2-4 and Figure S1, including ROI-outlined CT/DCE-MRI images, gross histology specimens, and DCE-MRI quantitative parametric pseudo-color images. Data were acquired from 12 Bama miniature pigs (approximately 6 months old, 25 kg) undergoing CT-guided single-needle pulmonary cryoablation, with immediate post-ablation contrast-enhanced CT and DCE-MRI, and histopathological validation with H&E staining. DCE-MRI parameters(Ktrans, kep, Ve, iAUC) were calculated using the two-compartment Tofts and Kermode model. cryoablation; lung; dynamic contrast-enhanced MRI (DCE-MRI); ablation margin; animal model; microcirculation 张国辉 EMBARGO https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
