Figure 5. — Kaplan-Meier survival curves of the patients with glioblastoma grouped according to MR perfusion imaging parameters: (A) rCBV OS and (B) PFS (CBV ≥1.3, n=27; rCBV <1.3, n=27); (C) rCBF OS and (D) PFS (rCBF ≥1.8, n=26; rCBF <1.8, n=24). There was no association between each of the MR perfusion imaging parameters and not only OS but also PFS in patients with glioblastoma. OS, Overall survival; PFS, progression-free survival; MGMT, O6-methylguanine DNA methyltransferase; rCBV, cerebral blood volume ratio; rCBF, cerebral blood flow ratio.
