- The study investigates the challenge of differentiating cerebral radiation necrosis (RN) from tumor recurrence after radiation treatment, noting existing diagnostic difficulties with standard MRI and the lack of evidence-based guidelines.
- A systematic review and meta-analysis were conducted on various imaging techniques, including MRI, MR Spectroscopy (MRS), and PET, analyzing data from 127 studies and 220 imaging datasets.
- Results showed that MRS had the highest sensitivity (90.7%) and DTI had the highest specificity (90.5%), with SPECT and MRS being ranked as the most effective options for differentiating RN from tumor recurrence in comparison to standard MRI.
