Susceptibility-weighted magnetic resonance (MR) perfusion imaging can identify low-grade gliomas that are destined to undergo malignant transformation months later, UK researchers report. This finding supports the use of MR perfusion imaging in monitoring tumor progression and guiding therapy. Reuters Health Information
