Which feature distinguishes ischaemic stroke from haemorrhagic stroke on first imaging?
Answer and explanation
Correct answer: A. CT shows no blood in ischaemic stroke
- Step 1: Non-contrast CT is the first test because it excludes haemorrhage quickly.
- Step 2: Thrombolysis is considered only after haemorrhage is excluded.
Answer
CT shows no blood in ischaemic stroke.
Why not the others: 'MRI is never used in stroke imaging' is incorrect since MRI is used for detail; 'Lumbar puncture is the first test' is not the first test; 'Chest X-ray separates the two' does not show brain pathology.
