Comparison of spatial and temporal pattern for fMRI obtained with BOLD and arterial spin labeling [PDF]

, 2006
Functional magnetic resonance imaging (fMRI) is presently either performed using blood oxygenation level-dependent (BOLD) contrast or using cerebral blood flow (CBF), measured with arterial spin labeling (ASL) technique.

Protein-induced changes in DNA structure and dynamics observed with noncovalent site-directed spin-labeling and PELDOR [PDF]

, 2012
Site-directed spin labeling and pulsed electron–electron double resonance (PELDOR or DEER) have previously been applied successfully to study the structure and dynamics of nucleic acids. Spin labeling nucleic acids at specific sites requires the covalent

Evaluating Vascular Hemodynamics in Cerebral Proliferative Angiopathy Using Advanced Arterial Spin Labeling MRI

Stroke: Vascular and Interventional Neurology
Cerebral proliferative angiopathy (CPA) is a rare vascular disorder that affects normal blood circulation in the brain. Although the structural changes in CPA can be characterized using standard radiologic modalities, assessing the vascular hemodynamics ...

Challenges to attention: A continuous arterial spin labeling (ASL) study of the effects of distraction on sustained attention [PDF]

NeuroImage, 2011
Maintaining attention and performance over time is an essential part of many activities, and effortful cognitive control is required to avoid vigilance decrements and interference from distraction. Regions at or near right middle frontal gyrus (Brodmann's area (BA) 9), as well as in other prefrontal and parietal areas, are often activated in studies of
