Experimental Cardiovascular Imaging (ExCaVI)
Our group is active in the research and development of dedicated techniques for in vivo magnetic resonance (MR) imaging and spectroscopy and their application to biomedical translational research including preclinical and clinical evaluation. In close collaboration with different partners within the University and the University Medical Center, tailored imaging and spectroscopy solutions are developed for a variety of preclinical and clinical applications. Activities range from basic MR technologies to application-specific optimization of the basic techniques for routine clinical evaluation. For multi-modal imaging purposes, close collaboration with the Departments of Nuclear Medicine and Radiology is established.
The group also runs the Core Facility Small Animal Imaging of the Medical Faculty of Ulm University and is part of the DFG funded Center for Translational Imaging MoMAN.

Infrastructure
Within the Cardiovascular MRI group, two whole-body MRI systems operating at
- 1.5T Philips Achieva, R5.1.7, 32 receive channels
- 3.0T Philips Achieva, R5.1.7, 32 receive channels
are available for clinical and methodological research. Both systems are fully equipped with high-performance gradient systems, dedicated cardiovascular imaging software and state-of-the-art receive coils relevant for cardiovascular imaging such as dedicated cardiac and carotid phased array coils.
A Research collaboration with Philips Medical Systems and Philips Research Europe is well established ensuring access to latest MRI technology and pulse programming software enabling the adaptation of the scanner SW to individual demands.
A dedicated small animal high-field MRI system (BioSpec 117/16, Bruker Biospin) equipped with an 8-channel receive system and prepared for 1H, 13C, 19F, 23Na, and 31P imaging and spectroscopy is available at the Core Facility Small Animal Imaging.
A dedicated high-resolution small animal CT system (GE eXplore) can be applied for in-vivo and in-vitro structural analysis. Spatial resolution limits are 28³µm³.
