Cerebral Blood Flow Testing
🧠 Comparison: Cerebral Blood Flow Testing vs Monitoring
| Term | Definition | Temporal Nature | Purpose | Example Tools |
|---|---|---|---|---|
| Cerebral Blood Flow Testing | One-time or episodic assessment of cerebral perfusion to answer a specific diagnostic question. | Snapshot / Single time point | Diagnosis or confirmation (e.g. brain death, no cerebral perfusion in TA-NRP) | CT/MR perfusion, radionuclide scan, transcranial Doppler (spot), angiography |
| Cerebral Blood Flow Monitoring | Continuous or repeated observation of cerebral perfusion over time. | Ongoing / Real-time or repeated | Trend analysis, intraoperative safety, critical care surveillance | Continuous TCD, cerebral NIRS, brain tissue oxygen sensors |
