CT Angiography in acute stroke (Revisiting the 4Ps of Imaging)

Imaging in acute stroke has traditionally focussed on the 4 Ps - Parenchyma, Pipes, Perfusion and Penumbra and has increasingly relied upon advanced techniques including Magnetic Resonance Imaging (MRI) to evaluate such patients. However as per European Magnetic Resonance Forum (EMRF) estimates, the availability of MRI scanners for the general population in India (0.5 per million inhabitants) is quite low as compared to Europe (11 per million) and USA (35 per million), with the vast majority of them only present in urban cities.

ABSTRACT BACKGROUNDAdvances in diagnostic imaging of stroke include multimodal techniques such as noninvasive angiography and perfusion imaging. We aimed to characterize trends in neuroimaging utilization among acute stroke patients. Utilization of multimodal imaging for acute stroke in the community has remained largely uncharacterized despite its increased adoption at academic medical centers. METHODSWe quantified neuroimaging utilization in the emergency department (ED) for 1,700 hyperacute stroke patients presenting

Abstract The purpose of this study was to quantitatively analyze the relationship between three dimensional arterial spin labeling (3D-ASL) and dynamic susceptibility contrast-enhanced perfusion weighted imaging (DSC-PWI) in ischemic stroke patients. Thirty patients with ischemic stroke were included in this study. All subjects underwent routine magnetic resonance imaging scanning, diffusion weighted imaging (DWI), magnetic resonance angiography (MRA), 3D-ASL and DSC-PWI on a 3.0T MR scanner. Regions of interest (ROIs) were drawn on the cerebral blood flow (CBF) maps (derived from ASL) and multi-parametric DSC pe...
