摘要
颅内动脉夹层在临床中较为少见,但在青年人颅内血管疾病中占比较大。高分辨率MR管壁成像是直接针对于血管壁的成像方法,以其高空间分辨率、高信噪比、重复性强的优势被广泛应用于临床。作者着重介绍了颅内动脉夹层在高分辨率MR管壁成像中的典型影像学表现,和对于内膜瓣、双腔征、管径改变及壁间血肿等特征的独特优势,弥补了传统管腔成像在夹层的诊断和鉴别诊断中的不足,为颅内血管夹层疾病的确诊和干预治疗提供有力依据。
Intracranial artery dissection is rare in the clinic,but could account for a large proportion of young patients with intracranial vascular diseases.High-resolution magnetic resonance imaging is a direct method of vessel wall imaging and widely used in clinical practice due to advantages including high spatial resolution,high signal-to-noise ratio and strong reproducibility.The article briefly introduces the typical findings of intracranial artery dissection in high-resolution magnetic resonance imaging and the unique advantages of features such as intimal flap,double-lumen,lumen diameter change and intramural hematoma.It makes up for the deficiency of traditional lumen imaging in the diagnosis and differential diagnosis of intracranial artery dissection,providing a strong basis for the diagnosis and intervention of intracranial vascular dissection.
