高分辨磁共振在颅内动脉疾病诊断中的研究进展

High resolution magnetic resonance in the diagnosis of intracranial arterial disease

各种颅内动脉疾病病因复杂,发病率高,特别是狭窄性颅内动脉疾病,在高分辨磁共振应用前,临床上常难以进行鉴别。高分辨磁共振是唯一可以在活体内观察颅内动脉管壁的检查,且其是可重复性、高场强、无辐射的无创性检查。不同狭窄性的颅内动脉疾病具有不同的管壁特征,高分辨磁共振在鉴别各种颅内动脉狭窄性疾病起着重要作用。随着高分辨磁共振的发展,可以逐渐实现精准的影像学诊断。本文对各种狭窄性颅内动脉疾病的高分辨磁共振研究进展做一综述。

The causes of various intracranial arterial diseases are complicated and the incidence is high, especially stenotic intracranial arterial disease. Before high-resolution magnetic resonance imaging, it is often difficult to distin- guish clinically. High-resolution magnetic resonance is the only test that can observe intracranial arterial wall in vivo, and it is a non-invasive examination with repeatability, high field strength, and no radiation. Different stenotic intracra- nial arterial diseases have different characteristics of the vessel wall. High-resolution magnetic resonance imaging plays an important role in identifying various intracranial arterial stenosis diseases. With the development of high-resolution magnetic resonance, accurate imaging diagnosis can be gradually achieved. This article reviews the advances in high- resolution magnetic resonance imaging of various stenotic intracranial arterial diseases.
