肝脏转移瘤消融术后疗效的影像学评价进展

Progress in imaging evaluation of curative effect after liver metastasis ablation

肝转移瘤消融术后边缘局部残留或复发很常见。MRI功能成像包括扩散加权成像(diffusion weighted imaging,DWI)、多b值DWI、动态对比增强(dynamic contrast enhanced,DCE)成像、影像组学等在消融后早期显示病灶残留、鉴别术后炎症增生改变与残留或复发灶等方面的价值较大。该文就上述影像学方法在肝脏转移瘤消融术后疗效评价中的应用作一综述。

Local residual or recurrence of the ablation margin is common with liver metastatics after ablation therapy.Functional MRI imaging,including diffusion weighted imaging(DWI),multi-b value DWI,dynamic contrast enhanced(DCE)imaging and radiomics show residual lesions early after ablation,and differentiates postoperative inflammatory changes and residual or recurrence is important.This article reviews the application of the above mentioned imaging methods in the evaluation of curative effect after liver metastasis ablation.
