Insights in the Rat Brain by High Resolution BOLD functional MRI
Authors Jörg U. Seehafer1,2 and Mathias Hoehn1 1 In-vivo-NMR Lab, MPI for Neurological Research, 2 medres - medical research GmbH, Cologne, Germany Functional MRI (fMRI) is a unique tool for studying brain activation in humans and animals. In addition to standard anatomical MRI, fMRI can provide information about function and intactness of different brain regions as well as neuronal pathways and workflow of information between such regions. The BOLD effect ... Continue reading

Optimizing Magnetic Nanoparticles with Magnetic Particle Imaging (MPI)
Magnetic nanoparticles that have the attribute of being manipulated by magnetic fields are a current hot research topic due to their potential benefits for therapeutic applications, imaging and biomedicine. This significant potential is driving developments in the field of Magnetic Particle Imaging (MPI), with producers of magnetic nanoparticles keen to exploit new methods for testing. Only by understanding a particle’s properties and characteristics, from surface chemistry to toxicity, can effective end-systems and solutions be devised. ... Continue reading

In vivo insight in the mouse brain tissue microstructure and connectivity by DT-MRI and fiber tracking
Until very recently, the study of neural architecture and its integrity in animal models was exclusively done by using histology-based imaging modalities applied to fixed brain tissue. A non-invasive detailed insight into the brain’s microstructure and axonal connectivity in vivo has only become possible since the development of diffusion tensor magnetic resonance imaging (DT-MRI). The technique relies on the phenomenon of diffusion of water molecules in tissue. For each voxel of the image the diffusion tensor describes the magnitude ... Continue reading

Functional Cardiac MR Imaging in Mice
Functional cardiac mr imaging (CMR) requires high muscle/blood contrast, full coverage of the cardiac cycle and high temporal resolution. For this purpose ECG is commonly used for cardiac gating. ECG being an electrical measurement is disturbed by interference with the magnetic field, which is pronounced at ultra high fields. The self gating technique IntraGate is a very helpful alternative for robust cardiac imaging without compromising the accuracy of the derived myocardial function parameters. ... Continue reading
