Extracellular diffusion quantified by magnetic resonance imaging during rat C6 glioma cell progression

Braz. j. med. biol. res; 50 (7), 2017
Solution reflux and edema hamper the convection-enhanced delivery of the standard treatment for glioma. Therefore, a real-time magnetic resonance imaging (MRI) method was developed to monitor the dosing process, but a quantitative analysis of local diffusion and clearance parameters has not been assessed...

Cerebral blood flow and vasoreactivity in aging: an arterial spin labeling study

Braz. j. med. biol. res; 50 (4), 2017
Regional cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) in young and elderly participants were assessed using pulsed arterial spin labeling (ASL) and blood oxygenation level-dependent (BOLD) magnetic resonance imaging (MRI) techniques in combination with inhalation of CO2. Pulsed ASL and ...
