Evaluation of Software‐Optimized Protocols for Acoustic Noise Reduction During Brain MRI at 7 Tesla

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background MR‐generated acoustic noise may be particularly concerning at 7‐Tesla (T) systems. Noise levels can be reduced by altering gradient output using software optimization. However, such alterations might influence image quality or prolong scan times, and these optimizations have not been well characterized.

Effect of Body Position on Dynamic Apparent Diffusion Coefficient Changes During the Cardiac Cycle in the Human Brain

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Dynamic changes in the apparent diffusion coefficient (ΔADC) during the cardiac cycle reflect water molecule fluctuations in the brain and intracranial conditions. While body position strongly affects intracranial conditions, the relationship between ΔADC and body position has been less explored, as conventional MRI is typically ...

Am I safe around you? Attachment figure activation increases perceived security but does not reduce negative interpretations of neutral expressions

open access: yesJournal of Traumatic Stress, EarlyView.
Abstract Child maltreatment (CM) is associated with social problems, such as loneliness and isolation. One factor that might contribute to these problems is the tendency for individuals who have experienced CM to interpret neutral facial expressions as negative (i.e., negativity bias).
