Journal ArticleDOI
Motor and language DTI Fiber Tracking combined with intraoperative subcortical mapping for surgical removal of gliomas.
Lorenzo Bello,A. Gambini,Antonella Castellano,Giorgio Carrabba,Francesco Acerbi,Enrica Fava,Carlo Giussani,Marcello Cadioli,Valeria Blasi,Alessandra Casarotti,Alessandra Casarotti,Costanza Papagno,Arun Kumar Gupta,Sergio M. Gaini,Giuseppe Scotti,Andrea Falini +15 more
TL;DR: The combination of DTI-FT and ISM decreased the duration of surgery, patient fatigue, and intraoperative seizures, and enhances surgical performance and safety maintaining a high rate of functional preservation.
Journal ArticleDOI
Diffusion limited oxygen delivery following head injury.
David K. Menon,Jonathan P. Coles,Arun Kumar Gupta,Tim D. Fryer,Peter Smielewski,Doris A. Chatfield,Franklin I. Aigbirhio,Jeremy N. Skepper,Pawan S. Minhas,Peter J. Hutchinson,T. Adrian Carpenter,John C. Clark,John D. Pickard +12 more
TL;DR: Increased diffusion barriers may reduce cellular oxygen delivery following head injury and attenuate the ability of the brain to increase oxygen extraction in response to hypoperfusion.
Journal ArticleDOI
Hyperventilation following head injury: effect on ischemic burden and cerebral oxidative metabolism.
Jonathan P. Coles,Tim D. Fryer,Martin R. Coleman,Peter Smielewski,Arun Kumar Gupta,Pawan S. Minhas,Franklin I. Aigbirhio,Doris A. Chatfield,Guy B. Williams,Simon Boniface,T. Adrian Carpenter,John C. Clark,John D. Pickard,David K. Menon +13 more
TL;DR: The acute cerebral blood flow reduction and increase in CMRO2 secondary to hyperventilation represent physiologic challenges to the traumatized brain and may represent a significant mechanism of avoidable neuronal injury following head trauma.
Journal ArticleDOI
Effect of cerebral perfusion pressure augmentation on regional oxygenation and metabolism after head injury.
Andrew J. Johnston,Luzius A. Steiner,Jonathan P. Coles,Doris A. Chatfield,Tim D. Fryer,Peter Smielewski,Peter J. Hutchinson,M. T. O’Connell,Pippa G. Al-Rawi,Franklin I. Aigbirihio,John C. Clark,John D. Pickard,Arun Kumar Gupta,David K. Menon +13 more
TL;DR: The results suggest that the ischemic level of brain tissue oxygen may lie at a level below 14 mm Hg (1.8 kPa); however, the data do not allow us to be more specific.
Journal ArticleDOI
Clinical applications of susceptibility weighted MR imaging of the brain - a pictorial review
Bejoy Thomas,Sivaraman Somasundaram,Krishnamoorthy Thamburaj,Chandrasekharan Kesavadas,Arun Kumar Gupta,Narendra Bodhey,Tirur Raman Kapilamoorthy +6 more
TL;DR: This unique MR sequence will help in detecting occult low flow vascular lesions, calcification and cerebral microbleed in various pathologic conditions and aids in characterizing tumors and degenerative diseases of the brain.
