Application of High-Resolution Magnetic Resonance Vessel Wall Imaging in Endovascular Treatment

Intracranial atherosclerotic disease (ICAD) is one of the most important causes of ischemic stroke and is also associated with some recurrent stroke. Safety and effective treatment of ICAD is an important precondition to improve the prognosis of patients. The current therapy for middle cerebral artery stenosis was medication and vascular intervention. Traditional assessment methods for intracranial artery, such as magnetic resonance angiography (MRA), computed tomography angiography (CTA) and digital subtraction angiography (DSA), could mainly assess the stenosis degree of the intracranial artery. While, the high-resolution magnetic vessel wall examination has been a pivotal image examination for diagnosing intracranial arterial disease and it provides a unique insight into the atherosclerotic lesions of vessel wall. Therefore, the study aims to explore the association between HRMRI-VWI enhancement for stroke recurrence in ICAS patients treated with MCA angioplasty.
