Diffusion-Weighted Imaging in the Follow-Up of Treated High-Grade Gliomas: Tumor Recurrence Versus Radiation Injury
Abstract:
Diffusion-weighted
(DW) MR imaging is a means to characterize and differentiate morphologic
features, including edema, necrosis, and tumor tissue, by measuring differences
in apparent diffusion coefficient (ADC). These researchers hypothesized that DW
imaging has the potential to differentiate recurrent or progressive tumor
growth from treatment- induced damage to brain parenchyma in high-grade gliomas
after radiation therapy.
