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...
Pixel-by-pixel analysis of dual contrast-enhanced MRI results in experimental strokeT., NagarajaR., PaudyalK., KarkiJ., EwingJ., FenstermacherR., Knight
(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...
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...
The weekly training frequency and duration for both resistance and endurance training were collected. 2.2. Magnetic Resonance Imaging (MRI) The Dixon technique is a fast and frequently used method for examining adipose tissue. A water-only (W) and fat-only signal (F) is generated due to the ...
The dataset contains four different MRI modulates for each patient: T1-weighted, T1-weighted post-contrast (T1C), T2-weighted, and T2-FLAIR. These sequences provide complementary information about the tumor and its surroundings, allowing for a more comprehensive analysis of the tumor’s ...
A kidney MRI can look for: Kidney cancer Chronic kidney disease Renal vein thrombosis Kidney stones or tumors Although the risk is still low, people withchronic kidney disease(CKD) do have a higher chance of developing problems if a contrast dye is used for their MRI. This is because people...
” Dynamic contrast enhanced MRI: “dynamic contrast enhanced” AND MRI, “blood brain barrier” AND MRI, “blood-brain barrier” AND MRI, “permeability imaging.” Cerebrovascular reactivity: cerebrovascular reactivity,”“blood oxygen level dependent “, vasodilatation AND MRI, vasoconstriction AND ...
We describe an analysis method that characterizes the correlation between coupled time-series functions by their frequencies and phases. It provides a unified framework for simultaneous assessment of frequency and latency of a coupled time-series. The an
In contrast, previous work in a mouse model with a different YFP expression pattern (YFP(H)-R6/2) found no axonal disruption7, suggesting that axonal pathology is spatially and temporally selective and dependent on the specific genetic model of HD. Diffusion MRI is a powerful method for non-...
