We acquired high\u2010resolution MRI (HR\u2010MRI) of the middle cerebral artery (MCA) in patients with chronic unilateral MCA occlusion and evaluated the MRI and clinical findings.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>We selected 20 consecutive patients who presented with unilateral MCA occlusion. Proton\u2010density weighted HR\u2010MRI of the occluded MCA was acquired using a 3.0 Tesla MRI. We surveyed the morphology of the MCA at the occluded segment. Symptoms, the presence of other stenotic arteries, and atherosclerosis risk factors were compared for patients grouped by different findings on HR\u2010MRI.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>MCA occlusions were classified into the following two groups: plugged MCA (13\/20) with a clear view of the MCA trunk or vanishing MCA (7\/20) with no MCA trunk visible in the Sylvian cistern.
