Figure 6

Average Ktrans values between NP types. No significant difference was detected between NPs despite differences in size and relaxivity. PLGA NPs, Pro-NP and Gd-DTPA show a significant increase (p < 0.01) in Ktrans in the focal injury as compared to contralateral brain. Inlay shows a scaled comparison between NPs on the contralateral side of the brain. Inlay shows scaled Ktrans values in contralateral brain by NP type.
