We have derived an imaging metric that combines T1-weighted DCE-MRI parameters and tumor volume to predict the distant metastasis (DM). Preliminary data indicate that the DCE-MRI parameter correlates well with a tumors DM. Patients at risk of DM are sometime undetermined even with PET scan until there is clinical decline or radiologic progression. In clinical practice, knowing which patients will have DM is important to the individualization of care. Thus, tumor volume and DCE-MRI parameters, specifically, the maximal values of the Ktrans,ve and vp can be useful methods for tailoring treatment and improving patient outcomes.
