TL;DR: A comparison study between 10 automatic and six interactive methods for liver segmentation from contrast-enhanced CT images provides an insight in performance of different segmentation approaches under real-world conditions and highlights achievements and limitations of current image analysis techniques.
Journal ArticleDOI
Dopaminergic Network Differences in Human Impulsivity
Joshua W. Buckholtz,Michael T. Treadway,Ronald L. Cowan,Neil D. Woodward,Rui Li,M. Sib Ansari,Ronald M. Baldwin,Ashley N. Schwartzman,Evan S. Shelby,Clarence E. Smith,Robert M. Kessler,David H. Zald +11 more
TL;DR: It is found that higher levels of trait impulsivity were predicted by diminished midbrain D2/D3 autoreceptor binding and greater amphetamine-induced DA release in the striatum, which was in turn associated with stimulant craving.
Journal ArticleDOI
Mesolimbic dopamine reward system hypersensitivity in individuals with psychopathic traits
Joshua W. Buckholtz,Michael T. Treadway,Ronald L. Cowan,Neil D. Woodward,Stephen D. Benning,Rui Li,M. Sib Ansari,Ronald M. Baldwin,Ashley N. Schwartzman,Evans S. Shelby,Clarence E. Smith,David A. Cole,Robert M. Kessler,David H. Zald +13 more
TL;DR: These findings suggest that neurochemical and neurophysiological hyper-reactivity of the dopaminergic reward system may comprise a neural substrate for impulsive-antisocial behavior and substance abuse in psychopathy.
Journal ArticleDOI
Dopaminergic mechanisms of individual differences in human effort-based decision-making.
Michael T. Treadway,Joshua W. Buckholtz,Ronald L. Cowan,Neil D. Woodward,Rui Li,Mohammed Ansari,Ronald M. Baldwin,Ashley N. Schwartzman,Robert M. Kessler,David H. Zald +9 more
TL;DR: The authors found that individual differences in DA function in the left striatum and ventromedial prefrontal cortex were correlated with a willingness to expend greater effort for larger rewards, particularly when probability of reward receipt was low.
Journal ArticleDOI
Quantitative pharmacokinetic analysis of DCE-MRI data without an arterial input function: a reference region model
Thomas E. Yankeelov,Jeffrey J. Luci,Martin Lepage,Rui Li,Laura Debusk,P. Charles Lin,Ronald R. Price,John C. Gore +7 more
TL;DR: A method is presented that compares the tissues of interest (TOI) curve shape to that of a reference region (RR), thereby eliminating the need for direct AIF measurement and allowing for quantitative assessment of tissue properties without having to obtain high temporal resolution images to characterize an AIF.
