Evaluating brain blood flow using contrast-enhanced ultrasound

Quantification of Cerebral Perfusion at the Patient's Bedside When Performing Contrast-enhanced Ultrasound in Neurointensive Care Patients

Observational Assistance Publique - Hôpitaux de Paris · NCT05893407

This study is testing a new ultrasound method to see if it can help doctors check blood flow in the brains of patients with recent brain injuries.

What this trial studies

This study aims to assess brain tissue perfusion in patients with acute brain injuries using contrast-enhanced ultrasound perfusion imaging (PerCEUS). It focuses on diagnosing brain tissue hypoperfusion by evaluating the heterogeneity of brain perfusion and correlating the results with standard multimodal monitoring techniques. The PerCEUS measurements will be performed at the bedside by a physician shortly after hospitalization, with data analyzed offline using specialized software. The study will involve selecting specific regions of interest in the brain to assess perfusion levels.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who are admitted to the intensive care unit for acute brain injuries confirmed by CT or MRI.

Not a fit: Patients who are pregnant or have contraindications to the contrast agent used in the study will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the diagnosis and management of acute brain injuries by providing real-time insights into brain perfusion.

How similar studies have performed: While the use of contrast-enhanced ultrasound for brain perfusion assessment is gaining interest, this specific approach is relatively novel and has not been extensively tested in similar studies.
