Imaging Advances for Central Nervous System Tumors.

Area of Science:

• Neuro-oncology
• Radiology
• Medical Imaging

Background:

• Central nervous system (CNS) tumors, including glioma and brain metastasis, are increasingly classified using integrated molecular and histological data.
• This shift necessitates corresponding advancements in neuroimaging techniques for accurate diagnosis and treatment planning.

Purpose of the Study:

• To review recent progress in standard and advanced imaging techniques for CNS tumors.
• To discuss the adaptation of imaging approaches to the new molecular-based tumor classification framework.
• To identify challenges in implementing advanced imaging for clinical use in CNS oncology.

Main Methods:

• Review of current literature on standard and advanced neuroimaging modalities.
• Analysis of imaging techniques in the context of molecular tumor classification.
• Discussion of challenges in differentiating tumor from treatment effects.

Main Results:

• Standard and advanced imaging techniques are evolving to meet the demands of molecularly classified CNS tumors.
• New imaging approaches are being developed to improve diagnostic accuracy and treatment monitoring.
• Significant challenges persist, particularly in distinguishing tumor recurrence from treatment-induced changes.

Conclusions:

• The integration of molecular data into CNS tumor classification requires parallel evolution in diagnostic and therapeutic imaging.
• Further research and development are crucial to overcome current limitations and fully realize the clinical potential of advanced neuroimaging.
• Enhanced imaging strategies are vital for precise management of CNS tumors in the era of personalized medicine.
