Perfusion of surgical cavity wall enhancement in early post-treatment MR imaging may stratify the time-to-progression in glioblastoma
Fig 4
A, MR images from a 53-year-old male patient with glioblastoma taken 3 weeks after concurrent chemo-radiation.
The contrast-enhanced MRI (left) and ASL (right) showed positive perfusion along surgical cavity wall enhancement. B, Follow-up images taken 4 months later after additional 5 cycles of temozolomide show that the SCWE becomes stabilized.
