Description
Adam Wright and co-workers present a data-driven method to segment pulsing brain vessels in functional MRI, in a 2024 paper. Functional scans hold rich fluid and vessel information, but vessel maps from other scan types misalign with them due to distortion. Their method works directly in functional scan space.
Large arteries and the brain's main venous sinus pulse with the heartbeat, giving them a distinct signal pattern the method exploits. Validation against hand-made ground truth in a local dataset went well. On a large ageing dataset with hundreds of participants and repeated scans, the segmentations were highly reproducible. The authors say the tool enables reliable fluid dynamics studies in these vessels.
