We
aim to assess the correlations between parameters measured on DCE-MRI and
18F-FDG PET in rectal cancer. We found positive correlations between kep
measured by DCE-MRI and SUV values measured by PET/CT. Our findings may
indicate that kep during contrast washout phase is better associated with
tumor metabolism than Ktrans which is influenced by multiple factors during
contrast uptake phase. kep may have the potential as a useful biomarker to
reflect biological characteristics of rectum cancer
