Figure 4. Magnetic resonance images at the diagnosis and last examination, focusing on the four non-boost lesions.

Figure 4

The images show CE T1-WIs (A-L); axial images (A, C, E, G, I, K); coronal images (B, D, F, H, J, L); three days before the initiation of WBRT (pre) (A-F); and 11.4 months after the WBRT initiation (G-L).

(A-L) These images are shown at the same magnification and coordinates under co-registration and fusions based on the pre-irradiation images. (A-F) Eight lesions are observed, most of them cystic, with some solid components (#1,3,6). Two small lesions (#11,12) are mainly solid. (G-L) At 11.4 months, all the four non-boost lesions (#8,9,11,12) had regressed or almost disappeared. 

CE: contrast-enhanced; WIs: weighted images; WBRT: whole-brain radiotherapy
