Oncology

Background:

Neuroimaging techniques have advanced, enabling earlier detection of central nervous system (CNS) neoplasms.
These techniques also assist in measuring treatment responses.
However, interpretation errors and technical artifacts can complicate clinical decision-making.

Purpose of the Study:

To review the role and limitations of neuroimaging in diagnosing and monitoring CNS neoplasms.
To highlight how imaging impacts therapeutic decisions and understanding of tumor behavior.

Main Methods:

Review of current neuroimaging modalities (MRI, CT) for CNS neoplasms.
Discussion of common challenges in image interpretation and artifact identification.
Consideration of emerging techniques for assessing tumor metabolism.

Main Results:

Neuroimaging improves early diagnosis and radiotherapy accuracy for CNS tumors.
Imaging aids in explaining adverse treatment responses and excluding non-neoplastic causes of deterioration.
Accurate tumor delineation remains a challenge despite technical improvements.

Conclusions:

Despite challenges, neuroimaging (MRI, CT) is crucial for managing CNS neoplasms.
Awareness of interpretation pitfalls and artifacts is essential for accurate clinical application.
Future metabolic imaging holds promise for deeper insights into CNS tumor pathology.
