Forecasting intracranial hypertension using multi-scale waveform metrics

Martin Jaggi, Walter Karlen

Objective: Acute intracranial hypertension is an important risk factor of secondary brain damage after traumatic brain injury. Hypertensive episodes are often diagnosed reactively, leading to late detection and lost time for intervention planning. A pro-ac ...

Comparison of 2D simultaneous multi-slice and 3D GRASE readout schemes for pseudo-continuous arterial spin labeling of cerebral perfusion at 3 T

Tobias Kober, Bénédicte Marie Maréchal, Tom Hilbert

Objective In this perfusion magnetic resonance imaging study, the performances of different pseudo-continuous arterial spin labeling (PCASL) sequences were compared: two-dimensional (2D) single-shot readout with simultaneous multislice (SMS), 2D single-sho ...

Dynamic spatiotemporal patterns of brain connectivity reorganize across development

Alessandra Griffa, Patric Hagmann, Marie Schaer, Emeline Mullier

Late human development is characterized by the maturation of high-level functional processes, which rely on reshaping of white matter connections, as well as synaptic density. However, the relationship between the whole-brain dynamics and the underlying wh ...

Discovery and validation of temporal patterns involved in human brain ketometabolism in cerebral microdialysis fluids of traumatic brain injury patients

Sarah Catherine Sonnay, Anirikh Chakrabarti, Nicolas Christinat, Mojgan Masoodi

Background: Traumatic brain injury (TBI) is recognized as a metabolic disease, characterized by acute cerebral glucose hypo-metabolism. Adaptive metabolic responses to TBI involve the utilization of alternative energy substrates, such as ketone bodies. Cer ...

Brain Edema in Chronic Hepatic Encephalopathy

Cristina Ramona Cudalbu

Brain edema is a common feature associated with hepatic encephalopathy (HE). In patients with acute HE, brain edema has been shown to play a crucial role in the associated neurological deterioration. In chronic HE, advanced magnetic resonance imaging (MRI) ...

Glucose transporter 2 mediates the hypoglycemia-induced increase in cerebral blood flow

Rolf Gruetter, Hongxia Lei

Glucose transporter 2 (Glut2)-positive cells are sparsely distributed in brain and play an important role in the stimulation of glucagon secretion in response to hypoglycemia. We aimed to determine if Glut2-positive cells can influence another response to ...

A human cerebral and cerebellar 8-channel transceive RF dipole coil array at 7T

Rolf Gruetter, Özlem Ipek, Jérémie Daniel Clément

PURPOSE: Dipole antennas that provide high transmit field penetration with large coverage, and their use in a parallel transmit setup, may be advantageous in minimizing B 1+ -field inhomogeneities at ultra-high field, i.e 7T. We have developed and evaluate ...

Vascular-targeted low dose photodynamic therapy stabilizes tumor vessels by modulating pericyte contractility

Paul Joseph Dyson, Georges Wagnières, Matthieu Philippe Emmanuel Zellweger, Tina Riedel

Vascular-targeted low-dose photodynamic therapy (L-PDT) was shown to improve chemotherapy distribution in malignant pleural tumors such as malignant pleural mesothelioma (MPM). However, the mechanisms triggered by L-PDT on the tumor vasculature are still d ...

Hypertonic Lactate to Improve Cerebral Perfusion and Glucose Availability After Acute Brain Injury

Pierre Magistretti, Jocelyne Bloch

Objectives: Lactate promotes cerebral blood flow and is an efficient substrate for the brain, particularly at times of glucose shortage. Hypertonic lactate is neuroprotective after experimental brain injury; however, human data are limited. ...

Distribution of superparamagnetic Au/Fe nanoparticles in an isolated guinea pig brain with an intact blood brain barrier

Francesco Stellacci, Paulo Henrique Jacob Silva

Diagnosis and treatment of brain disorders, such as epilepsy, neurodegenerative diseases and tumors, would benefit from innovative approaches to deliver therapeutic or diagnostic compounds into the brain parenchyma, with either a homogeneous or a targeted ...

Hyperpolarized C-13 Magnetic Resonance Spectroscopy Reveals the Rate-Limiting Role of the Blood-Brain Barrier in the Cerebral Uptake and Metabolism of L-Lactate in Vivo

Bernard Lanz, Mor-Miri Mishkovsky, Tian Cheng, Arnaud Comment, Josefina Adriana Maria Bastiaansen, Hikari Ananda Infinity Yoshihara, Sylvain Eric Lengacher, Yuhei Takado

The dynamics of L-lactate transport across the blood-brain barrier (BBB) and its cerebral metabolism are still subject to debate. We studied lactate uptake and intracellular metabolism in the mouse brain using hyperpolarized C-13 magnetic resonance spectro ...

Structural and functional brain imaging using extended-focus optical coherence tomography and microscopy

Paul James Marchand

Neuroimaging techniques aim at revealing the anatomy and functional organisation of cerebral structures. Over the past decades, functional magnetic resonance imaging (fMRI) has revolutionized our understanding of human cerebral physiology through its abili ...
