Group 1: 7T MRI & MRS - Phantom/fruit/human experiment (demonstration: 1h, hands on: 3h)
The participants will get hands-on experience on a human 7T MRI scanner and perform experiments with a phantom and a fruit (or a human if there is volunteer). This part includes: basic safety aspects, operation of an MRI system, preparation of an experimental setup (RF coil loaded with a phantom/human), demonstration and optimization of common MRI and MRS protocols to get different imaging contrast and spectra.
Teacher: Lijing Xin and Daniel Wenz
Group 2: 14T MRI & MRS - Phantom, ex-vivo, in vivo rat (demonstration: 1h, hands on: 3h)
The participants will get hands-on experience on the 14.1T preclinical MRI system. The basic parameters, tips and tricks to obtain high-quality scans and we will look together at the meaning of several scan parameters. We will also present the environment for in vivo scanning at 14.1T with the animal holding equipment, anesthesia units and physiology monitoring capabilities to perform metabolic experiments in best conditions. We will show how to prepare and place the rat in a stabilized position in the magnet holder, with physiology monitoring setups and how to position an RF coil for best signal induction and reception. We will show how to run localizer images, perform coil and B0 shim optimizations, run anatomical images with acquisition parameters. For 1H MRS, we will show how to position an acquisition voxel in the area of interest, optimize the shim and water suppression to get a reliable 1H spectrum, and how to evaluate its quality.

Or/and an additional session can be organised in the automn if the demand is strong.
