The
integration of imaging strategies such as dynamic contrast-enhanced MRI
(DCE-MRI) in early phase drug development can help elucidate the underlying
tumor physiology and assess drug efficacy. This study focuses on the
relationships between serological expression of soluble VEGF receptors and
DCE-MRI tracer kinetic parameters in a group of ovarian tumors. We observe striking relationships between
the serological markers, Ktrans
and vp that indicate
that DCE-MRI is sensitive to specific aspects of the angiogenic process in
these tumors.
