The purpose of this study was to validate DCE-MRI parameters such as blood flow (F), permeability surface area product (PS), fractional intravascular space (v1), and fractional extracellular extravascular space (v2), 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 (v1, v2, F, 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.
