Expertise and support provided to users

Measurement:
In vitro and in vivo MR measurements – materials, fixed biological samples, small animals (rat, mouse, rabbit).
Qualitative and quantitative MR imaging (T1-, T2-, T2*-weighted, 2D, 3D, multislice by FLASH, RARE, MGE, UTE, quantitative relaxometry, quantitative imaging of diffusion - DWI, DTI, DKI, perfusion – DCE, DSC, ASL).
Localized in vivo MR spectroscopy.

Animal use:
Assistance with animal use protocol preparation, correct and legal execution of the experiment.
Veterinary care and supervision during the measurement.
Sample collection for histology, immunohistochemistry, electron microscopy, deep freeze storage, fixation (subcontracting of these analyses is possible).
