MKI67 and glioblastoma: After comparing the contrast-enhanced T1-weighted image histogram parameters between the high-level and the low-level expression group, we found that the min, P01, P50, and P75 of IDH-wildtype glioblastoma in Ki-67 high-level expression group were higher than those of the Ki-67 low-level expression group, and each parameter was able to differentiate between the two groups of tumors.
