文摘
- •
Asymmetric cortical vessel sign (ACVS) can be found in internal carotid artery (ICA) stenosis.
- •
ACVS is associated with an increased volume of prolonged TTP and Tmax values.
- •
It is an independent predictor of short term outcome.
- •
ACVS can identify clinically relevant hypoperfusion in patients with ICA stenosis and contraindications for contrast agents.
