Multimodality Functional Imaging in Radiation Therapy Planning: Relationships between Dynamic Contrast-Enhanced MRI, Diffusion-Weighted MRI, and 18F-FDG PET

Figure 3

In this axial slice (bottom), is represented along (top) a voxel line at different stages of treatment (pretreatment, at 27.72 Gy, and at 33.38 Gy). We can see how increases with dose and the central U-shaped valley corresponding to the badly vascularized area is becoming increasingly narrow. In the upper left figure, we consider AIF from data of the carotid artery near brain, and in the lower left figure, we consider AIF from data of the carotid artery in neck.
