Hypothesis
Are we seeing the complete picture when we focus solely on regional changes?
Conclusion
Incorporating a global assessment of cerebral perfusion offers a more comprehensive approach to understanding neurodegenerative diseases.
Supporting Evidence
- ASL MRI has been instrumental in revealing cerebral blood flow patterns in neurodegenerative diseases.
- Global reductions in perfusion could predispose certain brain regions to more pronounced declines.
- A global perfusion ASL visual rating scale has been developed to assess broader cerebral perfusion context.
Takeaway
This study suggests that looking at both global and local blood flow in the brain can help doctors understand brain diseases better.
Methodology
The study proposes a two-step interpretative approach for ASL perfusion images, focusing first on global cerebral perfusion and then on regional changes.
Potential Biases
The manuscript does not mention any risks of bias.
Limitations
The manuscript does not provide specific limitations.
