采用微计算机断层扫描对肿瘤发展的评估和后续反应来治疗肺癌的小鼠模型

Overview

This article presents a method for detecting tumor nodule development in a mouse model of adenocarcinoma using micro-computed tomography (Micro CT). The technique allows for monitoring changes in nodule size over time and in response to treatment, enhancing the understanding of lung cancer progression.
