颈部增强磁共振血管成像(3D-CEMRA)是检查颈部血管的重要方法。三维对比剂增强MRA具有成像速度快、扫描视野大、检查血管多、安全无辐射的特点,受到了临床医师青睐,其图像质量明显优于常规MRA,且常规MRA(如TOF、PC法)受扫描时间、血流、呼吸、心搏等因素的影响较大。本文旨在讨论脑梗死或半侧肢体障碍患者浅静脉留置针留置方位不同对3D-CEMRA图像合格率的影响。
Cervical enhanced magnetic resonance angiography (3D-CEMRA) is an important method of examining the neck vessels. Three-dimensional contrast-enhanced MRA has the advantages of fast imaging speed, large scanning field of view, large number of blood vessels to be examined and safe radiation-free. It is favored by clinicians and its image quality is obviously superior to that of conventional MRA. MRA (such as TOF, PC method) Scan time, blood flow, respiration, heart rate and other factors have a greater impact. The purpose of this article is to investigate the effect of different indwelling orientations of the superficial venous catheter in patients with cerebral infarction or hemiplegia on 3D-CEMRA image qualification.
