Figure 4.

Subtraction image of the pre-RT T1+C (4a) from mid-RT (4b) and post-RT (4c) showing the increase in SI of SPC demonstrating the edema that developed from RT at mid-RT(4d,red arrow) and more at post-RT (4e,red arrow) with the dose grid propagated from CT to T1+C sequence (4f). Another subtraction of the pre-RT T2 (4g) from both the mid-RT (4h) as well as the post-RT (4i) showing the RT-induced increase in SI of the MPC at mid-RT (4J,green arrow) and post-RT (4k,green arrow), with the dose grid over T2 showing the MPC located in the high dose region (4l)
