We acquired high-resolution vessel wall MRI of MCA in patients with chronic unilateral MCA occlusion and evaluated the characteristics of MRI and clinical findings. We selected 17 consecutive patients who presented with unilateral MCA occlusion. High resolution PD-weighted TSE MRI with the saturation of arterial flow, were acquired the occluded MCA using 3T MRI. As the presence of MCA on MRI, MCA occlusion was classified plaqued MCA (13/17): the clear demonstration of MCA and atrophic MCA group (4/17): no MCA in the sylvian fissure. The vessel wall MRI might be a useful imaging tool that characterizes MCA occlusion in vivo.
