Systematic Review Between Resting-State fMRI and Task fMRI in Planning for Brain Tumour Surgery

Area of Science:

• Neuroimaging
• Neurosurgery
• Oncology

Background:

• Task-based functional MRI (T-fMRI) is standard for preoperative brain tumor mapping.
• Challenges exist with T-fMRI due to patient-specific factors.
• Resting-state functional MRI (Rs-fMRI) presents a potential alternative.

Purpose of the Study:

• To systematically review the utility of Rs-fMRI for preoperative mapping in brain tumor patients.
• To compare Rs-fMRI with T-fMRI and intraoperative direct cortical stimulation (DCS).
• To evaluate Rs-fMRI's role in treatment guidance and neurodegeneration prediction.

Main Methods:

• Systematic review of 18 studies involving 1035 brain tumor patients.
• Searched PubMed, Scopus, and Web of Science databases.
• Compared Rs-fMRI, T-fMRI, and intraoperative DCS results.

Main Results:

• Rs-fMRI is a sensitive and dependable preoperative mapping technique.
• Rs-fMRI precisely detects neural networks and identifies crucial functional regions.
• Rs-fMRI results align with intraoperative DCS findings.
• Rs-fMRI is particularly useful when T-fMRI is challenging.
• Rs-fMRI demonstrates value in preoperative screening and evaluation.

Conclusions:

• Rs-fMRI is a valuable tool for preoperative brain tumor assessment.
• Rs-fMRI aids in treatment planning, surgical outcome prediction, and clinical decision-making.
• Rs-fMRI enhances the clinical management of brain tumors.
