高分辨MR颅内血管壁成像技术研究及临床应用新进展

Recent advances in the study and clinical application of high resolution MR intracranial vascular wall imaging

颅内动脉病变导致的动脉狭窄是缺血性脑卒中的主要风险之一,其病因包括动脉粥样硬化、动脉夹层、动脉炎、烟雾病等。高分辨MR血管壁成像(high resolution magnetic resonance vascular wall imaging,HR-MR VWI)是目前唯一可在体进行颅内血管壁成像的无创检查技术,具有高空间分辨率、对比-噪声比等优势,能鉴别诊断颅内动脉粥样硬化、动脉夹层、动脉炎、烟雾病等,为临床诊断和指导治疗提供重要信息和依据。作者就3.0 T高分辨率MR颅内血管壁成像技术及临床应用进展予以综述。

Arterial stenosis caused by intracranial artery disease is one of the main risk factors of ischemic stroke. Its causes include atherosclerosis, arterial dissection, arteritis, moyamoya disease and so on. High resolution magnetic resonance imaging of vascular wall is the only non-invasive technology that can be used for intracranial vascular wall imaging in the present. It has the advantages of high spatial resolution, contrast noise ratio and can differentiate intracranial atherosclerosis, arterial dissection, arteritis and moyamoya disease. It provides important information and evidence for clinical diagnosis and treatment. The following is a summary of the progress in imaging technique research and clinical application of 3.0 T high resolution MR imaging of intracranial vascular wall.
