Quantitative measurements of brain perfusion are influenced by perfusion-modifiers.
Standardization of measurement conditions and correction for important modifiers is …

With the advancement of in vivo magnetic resonance imaging (MRI) technique, more
detailed information about the human brain at high altitude (HA) has been revealed. The …

The assessment of resting perfusion measures (mean transit time, cerebral blood flow, and
cerebral blood volume) with magnetic resonance imaging currently requires the presence of …

Background and purpose Cerebral hypoperfusion has been reported in patients with COVID-
19 and neurological manifestations in small cohorts. We aimed to systematically assess …

Key points Cognitive performance is impaired by hypoxia despite global cerebral oxygen
delivery and metabolism being maintained. Using arterial spin labelled (ASL) magnetic …

Resting state networks (RSN), which show the connectivity in the brain in the absence of any
stimuli, are increasingly important to assess brain function. Here, we investigate the changes …

BACKGROUND AND PURPOSE: Resting brain tissue perfusion in cerebral steno-occlusive
vascular disease can be assessed by MR imaging using gadolinium-based susceptibility …

Cerebral blood arrival and tissue transit times are sensitive measures of the efficiency of
tissue perfusion and can provide clinically meaningful information on collateral blood flow …

Purpose To demonstrate the feasibility of mapping cerebral perfusion metrics with BOLD
MRI during modulation of pulmonary venous oxygen saturation. Methods A gas blender with …

Introduction Dynamic susceptibility contrast (DSC) MRI allows clinicians to determine
perfusion parameters in the brain, such as cerebral blood flow, cerebral blood volume, and …
