What is the primary diagnostic step to identify bleeding in suspected hemorrhagic stroke?

• A. Non-contrast CT scan
• B. MRI
• C. EEG
• D. Carotid ultrasound

Answer: (A)

In acute stroke symptoms, the first thing clinicians need to know is whether there is bleeding in the brain, because that changes immediate treatment decisions (for example, giving clot-busting therapy would be dangerous if a bleed is present). A non-contrast CT scan is the fastest, most available test to detect acute intracranial bleeding. It can quickly show blood as hyperdense areas within the brain tissue or in the subarachnoid space, confirming a hemorrhage and guiding urgent management such as blood pressure control, reversal of anticoagulation if needed, and surgical considerations. MRI can detect hemorrhage as well and is more sensitive for certain types or older bleeds, but it takes longer to perform and is not as practical in the hyperacute setting. EEG isn’t used to diagnose bleeding, and carotid ultrasound assesses blood flow in the carotids rather than intracranial bleeding.
