The role of minimally invasive, locoregional therapies in cancer is increasingly driven by the detection of small asymptomatic disease either incidentally or under surveillance for a known primary malignancy. Percutaneous image-guided ablation has become established as a parenchyma-sparing tool in the management of small volume primary and metastatic disease in the liver as well as solitary renal masses. As ablation is non-extirpative, post-ablation imaging is critical for the assessment of treatment completion, recurrence, and complications. Within established regional cancer networks, understanding of normal post-ablation imaging appearances is essential for the early identification of primary treatment failure or local recurrence, which may be amenable to repeat treatment. We provide an imaging primer of two common ablation sites - kidney and liver - focusing on normal appearances and appreciation of local disease progression.
微创局部区域治疗在癌症治疗中的作用，越来越多地受到偶然发现的小的无症状疾病或对已知原发性恶性肿瘤进行监测的驱动。经皮图像引导下消融已成为一种保留实质的工具，用于治疗肝脏中的小体积原发性和转移性疾病以及孤立性肾肿块。由于消融是非切除性的，消融后成像对于评估治疗完成情况、复发和并发症至关重要。在已建立的区域癌症网络中，了解消融后正常的影像学表现对于早期识别可能适合重复治疗的原发性治疗失败或局部复发至关重要。我们提供了两个常见消融部位——肾脏和肝脏——的影像学入门知识，重点关注正常表现以及对局部疾病进展的认识。
