Ricky Medel,Stephen J. Monteith,W. Jeffrey Elias,Matt Eames,John Snell,Jason P. Sheehan,Max Wintermark,Ferenc A. Jolesz,Neal F. Kassell +8 more
TL;DR: Magnetic resonance-guided focused ultrasound surgery (MRgFUS) is a novel combination of technologies that is actively being realized as a noninvasive therapeutic tool for a myriad of conditions as discussed by the authors.
Minimally invasive treatment of intracerebral hemorrhage with magnetic resonance-guided focused ultrasound.
Stephen J. Monteith,Sagi Harnof,Ricky Medel,Britney Popp,Max Wintermark,M. Beatriz S. Lopes,Neal F. Kassell,W. Jeff Elias,John Snell,Matt Eames,Eyal Zadicario,Krisztina Moldovan,Jason P. Sheehan +12 more
TL;DR: The feasibility of transcranial MR-guided focused ultrasound sonothrombolysis in liquefying the clotted blood in ICH and thereby facilitating minimally invasive evacuation of the clot via a twist-drill craniostomy and aspiration tube is demonstrated in in vitro and cadaveric models of ICH.

Transcranial magnetic resonance-guided focused ultrasound surgery for trigeminal neuralgia: a cadaveric and laboratory feasibility study.
Stephen J. Monteith,Ricky Medel,Neal F. Kassell,Max Wintermark,Matt Eames,John Snell,Eyal Zadicario,Javier Grinfeld,Jason P. Sheehan,W. Jeff Elias +9 more
TL;DR: This study demonstrates focal heating of up to 18°C in a cadaveric trigeminal nerve at the REZ and along the cisternal segment with transcranial MRgFUS and in vivo studies are necessary to confirm the safety and efficacy of this potentially new, noninvasive treatment.
