Which test is used to diagnose a hemorrhagic stroke?

• A. Head CT
• B. MRI of brain
• C. Lumbar puncture
• D. Carotid ultrasound

Answer: (A)

Detecting intracranial bleeding quickly is crucial when a stroke is suspected. A non-contrast head CT is used because blood appears bright on CT scans and the test can be done rapidly in most emergency departments. This immediate imaging lets clinicians confirm a hemorrhage, rule out bleeding, and make fast, safe decisions about treatment choices. MRI of the brain can also detect bleeding and is very sensitive, but it takes longer to perform and isn’t as readily available in acute emergencies, which is why it isn’t the first line for this purpose. A lumbar puncture isn’t used to diagnose an acute bleed directly; it may be considered if subarachnoid hemorrhage is still suspected after a negative CT. Carotid ultrasound checks for blockages in the carotid arteries, not for acute brain bleeding, so it doesn’t diagnose a hemorrhagic stroke. So, the quickest and most reliable test to diagnose a hemorrhagic stroke in an emergency setting is a non-contrast head CT.
