Abstract: Abstract The structural complexity of the thalamus, due to its mixed composition of gray and white matter, make it challenging to disjoint and quantify each tissue contribution to the thalamic anatomy. This work promotes the… read more here.

Abstract: Susceptibility‐based blood oxygenation measurements in small vessels of the brain derive from gradient echo (GRE) phase and can provide localized assessment of brain function and pathology. However, when vessel diameter becomes smaller than the acquisition… read more here.

DOI: 10.1002/mrm.26637
Abstract: Recent advances in 3D‐PCMRI (phase contrast MRI) sequences allow for measuring the complex hemodynamics in cerebral arteries. However, the small size of these vessels vs spatial resolution can lead to non‐negligible partial volume artifacts, which… read more here.
