How do you know what type of stroke it is or what treatment is best?

• A. You can tell from symptoms alone.
• B. Physical examination alone
• C. Blood glucose level alone
• D. CT scan or MRI

Answer: (D)

Determining stroke type requires imaging. Clinical symptoms alone often overlap between ischemic and hemorrhagic strokes, so you can’t reliably tell which type it is just from how the patient presents or from a physical exam. Blood glucose levels can rise after a stroke but they don’t reveal the type or the best treatment. Imaging with a CT scan or MRI is essential because it shows whether there is bleeding or a clot. A CT scan is usually the first test in the emergency setting because it’s fast and can quickly exclude a hemorrhage, which is critical before giving clot-dissolving therapies. If the CT doesn’t show a bleed but suspicion remains for ischemia, MRI—especially diffusion-weighted imaging—can detect early ischemic changes and help assess the extent of tissue at risk. Advanced imaging like CT or MR angiography can identify vessel occlusions that may be treated with procedures like thrombectomy. So the best way to know what type of stroke it is and what treatment to pursue is imaging with CT or MRI, because it provides direct evidence of bleeding, infarct, and vascular status that clinical exam alone cannot determine.
