Quantification of the neurochemical profile using simulated macromolecule resonances at 3 T

Rolf Gruetter, Benoît Schaller, Lijing Xin, Cristina Ramona Cudalbu

The broad resonances underlying the entire (1) H NMR spectrum of the brain, ascribed to macromolecules, can influence metabolite quantification. At the intermediate field strength of 3 T, distinct approaches for the determination of the macromolecule signa ...

Handling macromolecule signals in the quantification of the neurochemical profile

Rolf Gruetter, Cristina Ramona Cudalbu

In vivo localized proton magnetic resonance spectroscopy (1H MRS) became a powerful and unique technique to non-invasively investigate brain metabolism of rodents and humans. The main goal of 1H MRS is the reliable quantification of concentrations of metab ...

In vivo metabolic profiling of glioma-initiating cells using proton magnetic resonance spectroscopy at 14.1 Tesla

Rolf Gruetter, Cristina Ramona Cudalbu

In the last decade, evidence has emerged indicating that the growth of a vast majority of tumors including gliomas is sustained by a subpopulation of cancer cells with stem cell properties called cancer initiating cells. These cells are able to initiate an ...

RETRACTED: Marker-independent identification of glioma-initiating cells

Rolf Gruetter, Cristina Ramona Cudalbu

Tumor-initiating cells with stem cell properties are believed to sustain the growth of gliomas, but proposed markers such as CD133 cannot be used to identify these cells with sufficient specificity. We report an alternative isolation method purely based on ...
