Understanding brain blood flow and metabolism in patients with brain lesions

Insights Into the Pathophysiology of Neurovascular Uncoupling in Patients with Brain Lesions.

NA · Erasme University Hospital · NCT06797661

This study is trying to understand how blood flow and metabolism in the brain are affected in patients with brain tumors like glioblastoma, glioma, and astrocytoma.

What this trial studies

This research investigates neurovascular uncoupling (NVU) in patients with brain lesions, particularly focusing on glioblastoma, glioma, and astrocytoma. Using a multimodal noninvasive imaging approach, including functional MRI and PET scans, the study aims to explore the mechanisms behind the relationship between brain metabolism, blood flow, and neuronal activity. By analyzing these interactions, the study seeks to improve the understanding of brain function in the context of brain tumors and their treatment.

Who should consider this trial

Good fit: Ideal candidates for this study are patients with a potentially resectable intra-cerebral mass lesion who have not yet undergone surgery, chemotherapy, or radiation.

Not a fit: Patients with previous brain surgery, respiratory failure, asthma, claustrophobia, or diabetes may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of brain imaging techniques, leading to better surgical outcomes for patients with brain tumors.

How similar studies have performed: While the specific approach of this study may be novel, similar studies have shown promise in understanding neurovascular coupling and its implications for brain imaging.
