摘要

脑部磁共振成像(MRI)可用于评估多种颅内病变。非对比 T2 加权成像是几乎所有神经成像方案中的常规获取序列。在脑成像中偶然发现各种脑血管病变的情况并不少见。无论研究的主要适应症如何,神经放射科医生都应评估常规 T2 加权图像中是否有偶发的脑血管病变。血管结构在 T2 加权图像上通常表现为低信号血流空泡。根据我们的经验,一般的神经放射科医生很容易发现大的脑血管异常。在本文中,我们将介绍各种颅内脑血管病变在常规非对比 T2 加权磁共振成像上的特征性成像表现。这些病变包括动脉瘤、动静脉畸形、动脉闭塞、毛细血管扩张、海绵畸形、硬脑膜动静脉瘘、moyamoya、增生性血管病和盖伦静脉畸形。

Intracranial cerebrovascular lesions on T2-weighted magnetic resonance imaging.

Magnetic resonance imaging (MRI) of the brain has been implemented to evaluate multiple intracranial pathologies. Non-contrast T2-weighted images are a routinely acquired sequence in almost all neuroimaging protocols. It is not uncommon to encounter various cerebrovascular lesions incidentally on brain imaging. Neuroradiologists should evaluate the routine T2-weighted images for incidental cerebrovascular lesions, irrespective of the primary indication of the study. Vascular structures typically demonstrate a low signal flow-void on the T2-weighted images. In our experience, large cerebrovascular abnormalities are easily visible to a typical neuroradiologist. In this article, we present the spectrum of the characteristic imaging appearance of various intracranial cerebrovascular lesions on routine non-contrast T2-weighted MRI. These include aneurysm, arteriovenous malformation, arterial occlusion, capillary telangiectasia, cavernous malformation, dural arteriovenous fistula, moyamoya, proliferative angiopathy, and vein of Galen malformation.
