In vivo measurement of glycine with short echo-time H-1 MRS in human brain at 7 T

Rolf Gruetter, Giulio Gambarota, Lijing Xin, Wietske Van der Zwaag, Gunnar Krüger

To determine whether glycine can be measured at 7 T in human brain with H-1 magnetic resonance spectroscopy (MRS). ...

Evolution of the neurochemical profile after transient focal cerebral ischemia in the mouse brain

Rolf Gruetter, Hongxia Lei

Evolution of the neurochemical profile consisting of 19 metabolites after 30 mins of middle cerebral artery occlusion was longitudinally assessed at 3, 8 and 24 h in 6 to 8 mu L volumes in the striatum using localized H-1-magnetic resonance spectroscopy at ...

Proton NMR of15N-choline metabolites enhanced by dynamic nuclear polarization

Arnaud Comment, Geoffrey Bodenhausen, Rolf Gruetter, Sami Jannin, Riddhiman Sarkar, Paul Romeo Vasos

(Figure Presented) Chemical shifts of protons can report on metabolic transformations such as the conversion of choline to phosphocholine. To follow such processes in vivo, magnetization can be enhanced by dynamic nuclear polarization (DNP). We have hyperp ...

Caffeine consumption attenuates neurochemical modifications in the hippocampus of streptozotocin-induced diabetic rats

Rolf Gruetter, João Miguel das Neves Duarte

Type 1 diabetes can affect hippocampal function triggering cognitive impairment through unknown mechanisms. Caffeine consumption prevents hippocampal degeneration and memory dysfunction upon different insults and is also known to affect peripheral glucose ...

The rate-limiting step for glucose transport into the hypothalamus is across the blood–hypothalamus interface

Rolf Gruetter, Hongxia Lei, Carole Poitry-Yamate

Specialized glucosensing neurons are present in the hypothalamus, some of which neighbor the median eminence, where the blood–brain barrier has been reported leaky. A leaky blood–brain barrier implies high tissue glucose levels and obviates a role for endo ...

Motion detection using FID navigator signals of MRI coil array elements

Rolf Gruetter, Gunnar Krüger, Tobias Kober, José Pedro Rebelo Ferreira Marques

We propose a motion-detection technique which, in contrast to previously suggested methods, is based on motion-induced free induction decay (FID) signal changes in receive coil arrays with negligible impact on scanning performance. ...

Steady-state brain glucose transport kinetics re-evaluated with a four-state conformational model

Rolf Gruetter, João Miguel das Neves Duarte, Hongxia Lei, Carole Poitry-Yamate

Glucose supply from blood to brain occurs through facilitative transporter proteins. A near linear relation between brain and plasma glucose has been experimentally determined and described by a reversible model of enzyme kinetics. A conformational four-st ...

Comparison of T-1 Relaxation Times of the Neurochemical Profile in Rat Brain at 9.4 Tesla and 14.1 Tesla

Rolf Gruetter, Lijing Xin, Cristina Ramona Cudalbu

Knowledge of T-1 relaxation times can be important for accurate relative and absolute quantification of brain metabolites, for sensitivity optimizations, for characterizing molecular dynamics, and for studying changes induced by various pathological condit ...
