  • Characterize the performance and biodistribution of novel MRI contrast agents at high field

Technical Details

9.4T MRI

The 9.4T Bruker Biospec MRI system (30 cm bore) is designed for hardware-intensive experiments such as high resolution imaging, functional imaging, and diffusion imaging. The large gradient set has an internal diameter of 20 cm and a gradient strength of 200 mT/m, and is suitable for imaging larger rodents such as rabbits and guinea pigs. The gradient insert with 12 cm diameter and a gradient strength of 450 mT/m is suitable for imaging mice and rats. An AutoPac laser positioning system enables rapid and precise sample positioning. The system has four receive channels for parallel imaging, and four transmit channels, including one for X-nuclei.


The 7T Bruker PharmaScan MRI system (16 cm bore) is designed for high throughput experiments for imaging anatomy and basic function. Its gradient set has a 9 cm bore suitable for imaging mice and rats, and a strength of 120 mT/m. Four receive channels enable parallel imaging.
