[Visualization of radiation effects on the central nervous system]

Area of Science:

• Neuroradiology
• Oncology
• Medical Imaging

Context:

• Cancer therapies like chemotherapy and radiation increase patient survival, leading to more frequent therapy-related side effects.
• Central nervous system (CNS) side effects are common and can manifest acutely or chronically.
• Distinguishing therapy-induced changes from tumor recurrence is a clinical challenge.

Purpose:

• To review common acute and chronic therapy-related changes in the CNS.
• To correlate these changes with magnetic resonance imaging (MRI) findings.
• To discuss the utility of advanced imaging techniques in differentiating treatment effects from tumor progression.

Summary:

• Therapy-related side effects are a significant cause of morbidity in cancer patients, often detectable by MRI.
• Acute CNS changes are typically reversible, whereas chronic changes can persist for years.
• Advanced MRI techniques like MR spectroscopy and perfusion measurements can aid in differential diagnosis.

Impact:

• Improved understanding of neuroimaging findings associated with cancer treatments.
• Enhanced ability to differentiate treatment-related changes from tumor progression, potentially improving patient management.
• Highlights the role of advanced MRI in assessing CNS toxicity and patient outcomes.
