Cerebral Oxygen Metabolism in Children with Sickle Cell Disease and Stroke

This study aims to understand how blood flow and metabolism affect brain development in children and young adults, especially those with Sickle Cell Disease or a history of stroke. Researchers will use magnetic resonance imaging (MRI) to measure how the brain's blood vessels expand and contract. During the MRI, participants will inhale carbon dioxide to see how their blood vessels react. The main goal is to measure your brain's oxygen metabolism during this 75-minute MRI scan. This research hopes to find ways to identify brain tissue at risk of permanent injury. The study is currently recruiting 350 participants, including healthy individuals.

Study design
This is an interventional study with a planned enrollment of 350 participants. It is not specified if it is randomized or blinded.
What's involved
You would participate in an MRI scan where you inhale carbon dioxide. The MRI scan itself will last about 75 minutes.
Compensation
Not stated in the trial record.
Follow-up
The primary measurement of cerebral oxygen metabolism occurs during the 75-minute MRI scan. No further follow-up is specified.
