Can a CT determine brain death?
CTA examinations confirmed brain death diagnoses in all patients who had clinical brain death diagnoses, and no confliction between CTA findings and clinical diagnoses was observed. Conclusion: Demonstrating the lack of cerebral circulation is a necessity for confirmation of brain death diagnosis.
How accurate is a CT angiogram brain?
CTA was 100% sensitive and specific in detecting complete occlusions seen on DSA. Using DSA as the gold standard, CTA detected ≥50% stenosis with a sensitivity of 97.1% (95% CI: 85 to 99.9%), a specificity of 99.5% (95% CI: 98.4 to 99.9%), and a NPV of 99.8% (95% CI: 98.7% to 100%; Table 2).
What does CT angiogram of brain show?
To find blood vessels that have become narrowed by atherosclerosis (fatty material that forms plaques in the walls of arteries) To find abnormal blood vessel formations inside your brain. To identify blood vessels damaged by injury.

What are the risks of having a brain angiogram?
What are the risks of cerebral arteriograms?
- Loss of consciousness.
- Transient ischemic attack (TIA, a brief stroke-like condition)
- Paralysis on one side of the body (hemiplegia)
- Blood clot in the blood vessel (embolus)
- Bleeding.
- A collection of blood and swelling (hematoma)
