Abstract Background Transcranial temporal interference stimulation (TIs) targeting the subthalamic nucleus (STN) is a novel noninvasive neuromodulation approach with potential to improve motor symptoms in Parkinson's disease (PD). However, its underlying neuroimaging mechanisms remain unclear.

Distinct Brain Drivers and Shared Cerebello–Cortical Input in ADCY5 and SGCE Hyperkinetic Movements
Resting‐state fMRI and effective connectivity revealed distinct cerebellar–basal ganglia–cortical interactions in ADCY5 (MxMD‐ADCY5) and SGCE (MYC/DYT‐SGCE) related movement disorders. The cerebellum modulated cortex directly in MYC/DYT‐SGCE, but indirectly via basal ganglia‐cerebellar projections in MxMD‐ADCY5, which also showed reduced subthalamic ...

ABSTRACT Purpose In diffusion MRI, vasogenic edema manifests as a major fraction of isotropic water that dilutes the anisotropic intra‐axonal portion of the signal. Many tractography algorithms mistake vasogenic edema for the white matter boundary and terminate tracking to prevent producing spurious streamlines.

ABSTRACT Purpose To directly quantify respiration‐driven cerebrovascular resistance dynamics (CRD) using a gas‐free MRI framework based on the internal‐to‐external artery carotid flow ratio (ratio_Q). Theory and Methods Two independent datasets (n = 10 and n = 17) were used to evaluate repeatability and to compare breathing conditions.

A Numerical Alternative to MR Thermometry for Safety Validation of Multi‐Channel RF Transmit Coils
ABSTRACT Purpose This study proposes a numerical technique to estimate peak local specific absorption rate (SAR) uncertainty of multi‐channel RF coils during the process of safety validation as an alternative to experimental temperature and electric‐field measurements, and demonstrates its use to enable human studies at 10.5 T.

Double Asymmetric Spin Echo EPI (dASE‐EPI) Enables fMRI of the Entire Rat Brain at 9.4 T
ABSTRACT Purpose Development and evaluation of a double asymmetric spin echo planar imaging (dASE‐EPI) sequence to balance sensitivity to blood oxygenation level‐dependent (BOLD) contrast with mitigation of susceptibility‐induced intravoxel spin dephasing in ultra high‐field rodent brain imaging.
