Imaging in Neuro-oncology
Elizabeth Coffee, Cleopatra Elshiekh, Joshua A. Budhu
TL;DR
This review discusses the role of imaging in diagnosing and managing brain tumors, covering current and emerging techniques for neuro-oncology care.
Contribution
The paper provides a comprehensive, clinically focused review of imaging modalities and innovations in neuro-oncology.
Findings
Standard and advanced imaging techniques are essential for diagnosing and monitoring brain tumors.
RANO criteria and emerging technologies like radiomics and AI are improving tumor assessment.
Equitable access to advanced imaging remains a significant challenge in neuro-oncology.
Abstract
Brain tumors are a diverse group of neoplasms that vary widely in treatment and prognosis. Imaging serves as the cornerstone of diagnosis, monitoring response to treatment and identifying progression of disease in neuro-oncologic care. This review outlines current and emerging imaging modalities with a focus on clinical application in glioma, meningioma, and brain metastasis. We cover standard imaging modalities, advanced magnetic resonance techniques such as perfusion and spectroscopic imaging, and nuclear imaging with positron emission tomography (PET), including amino acid PET. We summarize the standardized Response Assessment in Neuro-Oncology (RANO) criteria, and explore innovations in radiomics, artificial intelligence, and targeted imaging biomarkers. Finally, we address challenges related to equitable access to advanced imaging. This review provides a practical, clinically…
