Is edema of malignant glioma different from edema of other tumors? Analysis of time dependent diffusion image using ternary plot method

Motivation: The edema around a malignant glioma contains infiltrating tumor cells. The motivation for this study was to determine the characteristics of the edema of malignant glioma. Goal(s): The goal is to evaluate the characteristics of edema around malignant gliomas using a combination of the oscillating gradient spin echo and pulsed gradient spin echo. Approach: The ternary plot method is used to evaluate the characteristics of edema by using a plot of existing tissue as an internal reference. Results: Edema of malignant gliomas showed a different distribution in relation to the internal reference in the ternary plot method compared to edema of other tumors. Impact: Ternary plot method was used to present pixel values obtained from oscillating gradient spin echo and pulsed gradient spin echo, and existing tissues were evaluated as internal references, which was thought to enable evaluation of the histological properties of edema.
