At 4 hours an ischaemic stroke is in the hyperacute phase. The earliest non-contrast CT sign is the hyperdense vessel sign (clot in the MCA), seen in the first 0–6 hours.
- Progressive hypodensity, swelling and midline shift develop later (24 h to 1 week).
- Diffusion-weighted imaging is an MRI sequence, not a CT finding.
