将缺血性脑卒中分为5个亚型:心源性脑栓塞(cardioembolism)、大动脉粥样硬化性卒中(large-artery atherosclerosis)、小动脉闭塞(腔梗)(small-artery lacunar occlusion,lacune)、其他已知原因的缺血性脑卒中(stroke of otherdemonstrated etiology)包括由其他少见原因所致脑...
(Stroke 3) 通过对Michael Forsting教授上两期视频的学习,我们知道,急性出血性或缺血性卒中患者,均有必要做CT平扫和增强扫描。 众所周知,MRI在中枢神经系统的应用已经非常成熟,那对于卒中患者,MRI检查该何时用、如何用?本期视频Michael For...

magnetic resonance angiography, auniqueform of MRI technology, can be used to produce an image of flowing blood. This permits the visualization of arteries and veins without the need for needles, catheters, or contrast agents. As with MRI, these techniques have helped revolutionize biomedical ...
本文发表在International Journal of Stroke杂志。 引言 脑小血管疾病(cSVD)是缺血性和出血性中风以及血管性认知障碍的主要原因。它通常以在磁共振成像(MRI)上可见的多种组织改变为特征,包括但不限于白质高信号强度(WMH)、腔隙、脑微出血和扩大的脑血管周围空间。这些cSVD在MRI上的病变在临床实践中可用于诊断,其中...
Considering that MRI imaging, with its complex generation of contrast, is in principle more appropriate for displaying and differentiating soft tissue than CT, it would be advantageous to adapt conventional MRI stroke protocols for enhanced visualization of AIS thrombi and at the same time information...

BACKGROUND: The practice of administering intravenous contrast to children varies by institution depending on their routine. OBJECTIVES: To assess the necessity of routine contrast administration in brain magnetic resonance imaging (MRI) of pediatric outpatients referred for chronic headache workups. METHODS...
