KDR and neoplasm: The purpose of this project was to investigate whether the acquired functional CEUS parameters of tumor microcirculation and the molecular CEUS parameters of VEGFR2-specific binding can be applied as non-invasive imaging biomarkers of therapy response and correlate it with DCE-MRI parameters of tumor microcirculation, to acquire a composite functional and molecular biomarker panel with complementary information of tumor angiogenesis, validated by immunohistochemistry as standard of reference.
