The combination of baseline magnetic resonance perfusion-weighted imaging-derived tissue volume with severely prolonged arterial-tissue delay and diffusion-weighted imaging lesion volume is predictive of MCA-M1 recanalization in patients treated with endovascular thrombectomy

IntroductionIndices of collateral flow deficit derived from MR perfusion imaging that are predictive of MCA-M1 recanalization after intravenous thrombolysis have been recently reported. Our objective was to test the performance of such MRI-derived co

Abstract TP56: Insight Into Human Ischemia Reperfusion Injury in Acute Stroke: A Voxel-Based MRI Analysis of Tissue Fate

Autor: May Nour, Fabien Scalzo, Jeffery R Alger, Sidney Starkman, Latisha K Ali, Doojin Kim, Paul M Vespa, Neal M Rao, Anil Yallapragada, Jeffery L Saver, Noriko Salamon, David S Liebeskind, for the UCLA Stroke Investigators

Publikováno v: Stroke. 44

Background: Reperfusion is characterized by initial restriction of blood supply followed by subsequent vascular restoration and concomitant reoxygenation of downstream tissue. In spite of mitigating initial tissue hypoxia, exacerbation of tissue inju

Multi-delay multi-parametric arterial spin-labeled perfusion MRI in acute ischemic stroke - Comparison with dynamic susceptibility contrast enhanced perfusion imaging

Autor: Wang, Danny JJ, Alger, Jeffry R, Qiao, Joe X, Gunther, Matthias, Pope, Whitney B, Saver, Jeffrey L, Salamon, Noriko, Liebeskind, David S, UCLA Stroke Investigators

The purpose of the present study was to present a multi-delay multi-parametric pseudo-continuous arterial spin labeling (pCASL) protocol with background suppressed 3D GRASE (gradient and spin echo) readout for perfusion imaging in acute ischemic stro

P-019 Clinical Conviction: Selection Bias In Recent Endovascular Stroke Trials

Autor: G Duckwiler, Satoshi Tateshima, Sidney Starkman, Ucla Stroke Investigators, David S Liebeskind, Sunil A Sheth, Reza Jahan, Nestor R Gonzalez, Jeffery L Saver

Publikováno v: Journal of NeuroInterventional Surgery. 6:A30.2-A31

Introduction Differing biases may affect enrollment patterns and result in trial participants that are not representative of clinical practice nor ideal candidates for therapy. We sought to evaluate the stringency of inclusion/exclusion criteria for
