Figure 8. Serial magnetic resonance images before and after the radiotherapy, mainly focusing on the right hemisphere lesions.

Figure 8

The images show CE T1-WIs (A-P); axial images (A-H); sagittal images in the right hemispheres (I-P); before the SRS boost (at 8 fr of the WBRT) (A, E, I, M); at 1.7 months after the initiation of WBRT (29 days after the completion of SRS boost) (B, F, J, N); at 4 months after the WBRT initiation (C, G, K, O); and at 11.4 months (D, H, L, P).

(A-P) These images are shown at the same magnification and coordinates under co-registration and fusion based on the pre-SRS images. All the seven lesions remarkably shrunk at 1.7 months and further regressed after that at 11.4 months, with the solid components almost disappearing.

CE: contrast-enhanced; WIs: weighted images; SRS: stereotactic radiosurgery; fr: fractions; WBRT: whole-brain radiotherapy
