Journal ArticleDOI
Perfusion functional MRI reveals cerebral blood flow pattern under psychological stress
Jiongjiong Wang,Hengyi Rao,Gabriel S. Wetmore,Patricia M. Furlan,Marc Korczykowski,David F. Dinges,John A. Detre +6 more
TL;DR: The results provide neuroimaging evidence that psychological stress induces negative emotion and vigilance and that the ventral RPFC plays a key role in the central stress response.
Journal ArticleDOI
A theoretical and experimental investigation of the tagging efficiency of pseudocontinuous arterial spin labeling.
TL;DR: In this paper, pseudocontinuous arterial spin labeling (pCASL) was proposed for noninvasively measuring arterial flow by magnetically tagging the protons in arterial blood.
Journal ArticleDOI
Empirical optimization of ASL data analysis using an ASL data processing toolbox: ASLtbx.
Ze Wang,Geoffrey K. Aguirre,Hengyi Rao,Jiongjiong Wang,María A. Fernández-Seara,Anna Rose Childress,John A. Detre +6 more
TL;DR: It was found that CBF calculations should be performed prior to spatial normalization and that modeling of global fluctuations yielded significantly increased peak t value in motor cortex.
Journal ArticleDOI
Gender difference in neural response to psychological stress
Jiongjiong Wang,Marc Korczykowski,Hengyi Rao,Yong Fan,John Pluta,Ruben C. Gur,Bruce S. McEwen,John A. Detre +7 more
TL;DR: This study used perfusion based functional magnetic resonance imaging to measure cerebral blood flow responses to mild to moderate stress in 32 healthy people and may represent an initial step in uncovering the neurobiological basis underlying the contrasting health consequences of psychosocial stress in men and women.
Journal ArticleDOI
Comparison of quantitative perfusion imaging using arterial spin labeling at 1.5 and 4.0 Tesla.
Jiongjiong Wang,David C. Alsop,Lin Z. Li,John Listerud,Julio B. Gonzalez-At,Mitchell D. Schnall,John A. Detre +6 more
TL;DR: The theoretical framework for the dependence of the ASL signal on the static field strength is provided, followed by experimental validation in which a multislice pulsed ASL (PASL) technique was carried out at 4T and compared with PASL and continuous ASL techniques at 1.5T, both in the resting state and during motor activation.
