This course is designed to introduce the various imaging modalities and suitable animal models for preclinical
studies exemplified by tumor heterogeneity of gastrointestinal and lung cancer. We focus on the clinically
available imaging methods CT, PET, DW-MRI and MRSI with hyperpolarized substances. In theoretical
lectures, students will learn about physics of different imaging methods and tumor-specific features that can
be exploit by imaging. Endogenous and transplanted rodent tumor models and clinical applications of
