简要总结
Magnetic resonance spectroscopy (MRS) allows non-invasive measurement of the concentration of up to 18 metabolites in the brain ("neurochemical profile").
The objective of this proposal is to develop new methods for high-field brain MRS (3 to 7 Tesla).
Our main hypothesis is that higher magnetic fields lead to improved spatial and temporal resolution and improved quantification precision.
Aims
- To obtain improved "neurochemical profiles" in the brain using single voxel proton MRS at very high field (3 Tesla to 7 Tesla).
- To develop new methods for proton magnetic resonance spectroscopic imaging (MRSI) to obtain metabolic maps at very high field (3 Tesla to 7 Tesla).
Since this project is focused on technical development, only healthy volunteers will be recruited (no patients).

时间窗: One time only
This protocol is devoted exclusively to technical development and testing of MRS methods on our MR scanners. As such, there is no well-defined outcome measure or time frame. It is a continuous effort. We recruit subjects on an ongoing basis to test, optimize, and assess the performance of newly developed techniques.
