Developing a Cerebral Blood Flow Atlas for Blood Flow Mapping

Begin with a cerebral blood flow, or CBF map generated by magnetic resonance imaging-arterial spin labeling, a noninvasive method for measuring blood flow in the brain tissue.

Obtain a structural brain image and, using computational tools, segment the cerebral regions into functional regions.

Generate triplanar views, showing cross-sectional images of the brain in three planes, with each segmented region displayed in distinct colors to represent functional areas.

Integrate the CBF data with the segmented regions to map blood flow values to specific brain areas.

Bright colors indicate high blood flow, while warm shades represent low levels.

Use algorithms to process the CBF data and create an atlas for comparing blood flow levels across brain regions.

The fluctuating red line highlights the average CBF across regions, quantifying blood flow.

The atlas colors correspond to the color bar and represent the probability of blood flow levels in specific brain regions-red indicates a high probability, while blue indicates a low probability.
