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...
The combination of CT or MRI with contrast enhanced or native angiographic methods has replaced the need for invasive angiographic vessel diagnosis. Cr and MRI show acute ICH with almost 100% sensitivity. The European (EUSI) and the American (AHA) stroke councils consider both modalities to be ...
For this reason, intravenous Gadolinium-enhanced MRI is used to generate contrast within the liver, based on differences in perfusion and capillary permeability. Likewise, the 𝜌ρm, T1, and T2 changes in gray and white due to acute stroke are also very small. Detection of acute stroke uses...

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...
Introduction We investigated the effect of increased tumor perfusion using dynamic susceptibility-contrast magnetic resonance imaging (DSC-MRI) in glioblastoma (GBM) patients on the surrounding ipsilateral brain tissue with respect to perfusion of the normal, unaffected contralateral brain and of the tumor...
我们描述的高级MRI技术正在提供cSVD的新的病理生理学见解,并允许更好地量化疾病负担和进展。它们在临床试验中有应用,既在评估新的治疗机制,也作为评估干预对实质组织损伤有效性的敏感终点。我们还讨论了这些高级技术的挑战,并提出了研究的未来方向。本文发表在International Journal of Stroke杂志。
There are many reasons to have MRI. MRI may find bleeding, such as bleeding in the brain; brain changes as instroke; problems with your back, such as aherniated disc; and an injury inside the body, such as a tornanterior cruciate ligament. ...
