Multi-parametric MRI of rectal cancer - Do quantitative functional MR measurements correlate with radiologic and pathologic tumor stages?

This study illustrates that ADC as well as MR perfusion values can be analyzed with good interobserver agreement in patients with rectal cancer. Moreover, MR perfusion parameters may allow accurate differentiation of tumor stages. Both findings suggest that functional MRI parameters may help to discriminate T and N stages for clinical decision making.
