Value of vessel wall magnetic resonance imaging in the diagnosis and management of cerebrovascular diseases

Abstract

Abstract Background Intracranial atherosclerosis, one of the leading causes of ischemic stroke, is associated with an increased risk for recurrent stroke and dementia. Objective This work was carried out to assess suspicious lesions detected by Magnetic Resonance Angiography (MRA) and Computed Tomgraphy Angiography (CTA) for further evaluation by vessel wall MRI . Patients and methods This study was conducted on 16 patients who were admitted to Ain Shams University Specialized Hospital with establilished diagnosis of stroke (11 patients with intracranial atherosclerosis, 3 patients with CNS vasculitis and 2 patients with Moya-moya disease ) performing MRI brain including magnetic resonance angiography (MRA) that showed intracranial stenosis, who then referred to Misr Radiology Center for the evaluation of intracranial vasculopathies by vessel wall MR Imaging using 3.0-tesla (T) field strengths. Results The results showed statistically significant difference between groups as regard to significant intracranial stenosis (>50%). It was prominent among moya moya disease group (100.0%) followed by intracranial atherosclerotic groups (81.8%), whereas CNS vasculitis group shows mild intracranial stenosis (0.0%). Conclusion Intracranial vessel wall MR imaging is an adjunct to conventional angiographic imaging
