While
there is a good understanding of microvascular function and structure described by tracer kinetic model-based
analyses of dynamic contrast-enhanced (DCE)-MRI data, the interpretation of
apparent water diffusion coefficient (ADC) is less clear. Besides ADC, the
parameter that is most sensitive to the water distribution and geometry is T1. In this study, we
acquire DCE-MRI and diffusion weighted images from a group of ovarian tumors
and find significant relationships between ADC, T1, and ve
that offer insight into the physiological meaning of these parameters in
ovarian tumors.
