Objective:

To investigate APTw CEST MRI signal characteristics in therapy-naive glioblastoma and their associations with clinical parameters and molecular features, highlighting their potential clinical significance.

Key Findings:
  • APTw CEST MRI can differentiate glioblastoma grades and IDH mutation status, which may influence treatment strategies.
  • Methylation-based classification reveals distinct molecular subgroups within IDH-wildtype glioblastoma, potentially guiding personalized therapy.
  • The mesenchymal subtype shows limited benefit from extensive surgical resection compared to other subtypes, indicating a need for tailored approaches.
Interpretation:

APTw CEST MRI provides valuable insights into the molecular diversity of glioblastomas, potentially guiding treatment decisions and prognostic assessments, thereby enhancing patient management.

Limitations:
  • Study limited to a single center with a relatively small sample size, which may affect generalizability.
  • Potential biases in patient selection and imaging quality could influence the results and their interpretation.
Conclusion:

APTw CEST MRI may serve as a non-invasive biomarker for understanding tumor heterogeneity and guiding clinical management in glioblastoma, emphasizing the need for further validation in larger cohorts.
