Measurement of PTE by means of MRI T2-weighted images. (a) MRI T2-weighted images showing PTE (peritumoral edema) extending less than 1 cm from the tumor margin; (b) MRI T2-weighted images showing PTE extending more than 1 cm from the tumor margin. Blue circle represented the size of PTE; red circle represented the size of tumor.
