Abstract

The purpose of this study was to validate DCE-MRI parameters such as blood flow (), permeability surface area product (PS), fractional intravascular space (), and fractional extracellular extravascular space (), obtained using a standard two-compartment model against other established analysis methods and histological indices. DCE-MRI datasets of 28 mice implanted with various human cancer xenografts were acquired and analyzed. Statistically significant correlations were found between the parameters derived from the standard two-compartment model (, , , and PS) with the histological markers of intravascular and interstitial space and with the corresponding flow and permeability estimates obtained by the initial slope method and Patlak plot, respectively.
