Torbey,May Kim-Tenser,Thabele M Leslie-Mazwi,Amrou Sarraj,Scott E. Kasner,Sameer A. Ansari,Sharon D.

Broderick,Maarten G Lansberg +25 more
TL;DR: Endovascular thrombectomy for ischemic stroke 6 to 16 hours after a patient was last known to be well plus standard medical therapy resulted in better functional outcomes than standard medical Therapy alone among patients with proximal middle‐cerebral‐artery or internal‐carotid‐arterY occlusion and a region of tissue that was ischeMIC but not yet infarcted.
Journal ArticleDOI
Recommended Implementation of Arterial Spin Labeled Perfusion MRI for Clinical Applications: A consensus of the ISMRM Perfusion Study Group and the European Consortium for ASL in Dementia
David C. Alsop,John A. Detre,Xavier Golay,Matthias Günther,Jeroen Hendrikse,Luis Hernandez-Garcia,Hanzhang Lu,Bradley J. MacIntosh,Bradley J. MacIntosh,Laura M. Parkes,Marion Smits,Matthias J.P. van Osch,Danny J.J. Wang,Eric C. Wong,Greg Zaharchuk +14 more
TL;DR: This review provides a summary statement of recommended implementations of arterial spin labeling (ASL) for clinical applications and describes the major considerations and trade‐offs in implementing an ASL protocol and provides specific recommendations for a standard approach.
Journal ArticleDOI
MRI profile and response to endovascular reperfusion after stroke (DEFUSE 2): a prospective cohort study.
Maarten G Lansberg,Matus Straka,Stephanie Kemp,Michael Mlynash,Lawrence R. Wechsler,Tudor G Jovin,Michael J Wilder,Helmi L. Lutsep,Todd Czartoski,Richard A. Bernstein,Cherylee W.J. Chang,Steven Warach,Franz Fazekas,Manabu Inoue,Aaryani Tipirneni,Scott Hamilton,Greg Zaharchuk,Michael P. Marks,Roland Bammer,Gregory W. Albers +19 more
TL;DR: Target mismatch patients who had early reperfusion after endovascular stroke treatment had more favourable clinical outcomes and a randomised controlled trial of endov vascular treatment for patients with the target mismatch profile is warranted.
Journal ArticleDOI
Comparative overview of brain perfusion imaging techniques
Max Wintermark,M. Sesay,Emmanuel L. Barbier,Katalin Borbély,William P. Dillon,James D. Eastwood,Thomas C. Glenn,Cécile Grandin,Salvador Pedraza,Jean F. Soustiel,Tadashi Nariai,Greg Zaharchuk,J.-M. Caille,Vincent Dousset,Howard Yonas +14 more
TL;DR: A comparative overview established by consensus among specialists of the various techniques dedicated to brain hemodynamics is presented, to offer a clearer picture of the pros and cons of currently available brain perfusion imaging techniques.
Journal ArticleDOI
Evidence of a cerebrovascular postarteriole windkessel with delayed compliance.
Joseph B. Mandeville,John J. A. Marota,Cenk Ayata,Greg Zaharchuk,Michael A. Moskowitz,Bruce R. Rosen,Robert M. Weisskoff +6 more
TL;DR: In this paper, a mismatch was observed between the responses of relative cerebral blood volume (rCBV) measured by magnetic resonance imaging and relative cerebral flow measured by laser-Doppler flowmetry in rat somatosensory cortex after electrical forepaw stimulation.
