Measurement of Blood-Brain Barrier Permeability with T₁-Weighted Dynamic Contrast-Enhanced MRI in Brain Tumors: A Comparative Study with Two Different Algorithms

Figure 2

A statistically significant correlation was observed between mean 𝐾^trans and tumor grade for both Patlak algorithm ((a): 𝑟=0.54(𝑃=0.004)) and for the ETK model ((b): 𝑟=0.58(𝑃=0.002)).
