Pancreatic ductal adenocarcinoma (PDAC) is the leading cause of cancer deaths worldwide. Quantitative multiparametric magnetic resonance imaging (mpMRI) allows for measuring the tumor's physiological characteristics, such as cellularity and vascularity/permeability. This study aimed to evaluate tumor physiology using mpMRI after single-fraction irradiation in a mouse model. The results demonstrated the changes in the functional status of mpMRI metrics. They were validated with in vivo histology markers of tumor perfusion (Hoechst 33342) and tissue morphology (Hematoxylin and eosin staining).
