Journal ArticleDOI
Linear and Nonlinear Relationships between Neuronal Activity, Oxygen Metabolism, and Hemodynamic Responses
Sameer A. Sheth,Masahito Nemoto,Michael Guiou,Melissa J. Walker,Nader Pouratian,Arthur W. Toga +5 more
TL;DR: The results indicate that caution is required in the interpretation of perfusion-based indicators of brain activity, such as functional magnetic resonance imaging (fMRI), and may help to refine quantitative models of neurovascular coupling.
Journal ArticleDOI
Gamma Knife surgery for Cushing's disease.
Jay Jagannathan,Jason P. Sheehan,Nader Pouratian,Edward R. Laws,Ladislau Steiner,Mary Lee Vance +5 more
TL;DR: In this article, the efficacy and safety of Gamma Knife surgery (GKS) in patients with adrenocorticotropic hormone-secreting pituitary adenomas was addressed, and the successful endocrine outcome after GKS was defined as a normal 24-hour urinary free cortisol (UFC) concentration after a minimum of 1 year of follow up.
Journal ArticleDOI
Incidence of symptomatic hemorrhage after stereotactic electrode placement
Charles A. Sansur,Robert C. Frysinger,Nader Pouratian,Kai-Ming G. Fu,Markus Bittl,Rod J. Oskouian,Edward R. Laws,W. Jeffrey Elias +7 more
TL;DR: Hypertension is a significant risk factor for hemorrhage in patients with various diseases treated with stereotactic electrode placement, and the effect of comorbidities on the risk of ICH is evaluated.
Journal ArticleDOI
Impact of the Accreditation Council for Graduate Medical Education work-hour regulations on neurosurgical resident education and productivity.
Jay Jagannathan,G. Edward Vates,Nader Pouratian,Jason P. Sheehan,James T. Patrie,M. Sean Grady,John A. Jane +6 more
TL;DR: An analysis of the UVA experience suggested that the 80-hour workweek leads to a notable increase in on-call duty hours with a profound decrease in the number of hours spent in conference and the operating room.
Journal ArticleDOI
Gamma Knife surgery for pituitary adenomas: factors related to radiological and endocrine outcomes
TL;DR: Smaller adenoma volume improves the probability of endocrine remission and lowers the risk of new pituitary hormone deficiency with GKS, and a higher margin dose offers a greater chance of endocrin remission and control of tumor growth.
