MicroMRI Laboratory

9.4T microMRI and stage for rodent set up including anesthesia.

A high field (9.4 Tesla) MRI Laboratory for high-resolution magnetic resonance (in-vivo spectroscopy) includes a Superconducting Magnet System MRBR 9.4T/210 AS controlled by a Bruker Avance console. The system is equipped with actively shielded gradients, capable of producing a gradient strength of 950 mT/m. The magnet is installed in a 1000-sq-ft newly refurbished facility located in the Medical Department, Bldg. 490. Multi-echo, 3D FT and EPI capabilities are available. The system is capable to do diffusion, perfusion, functional, high resolution anatomical imaging as well as multinuclear imaging and spectroscopy. The facility is also equipped with a state-of-the-art animal surgery laboratory with anesthesia equipment, surgical operating microscope, blood gas analyzer, laser Doppler flowmetry and a real-time physiological and computerized equipment for small-animal (rodent) imaging experiments.

MicroMRI research

Research at the BNL-SBU 9.4T MicroMRI Laboratory is diverse. Importantly all projects are carried out as collaboration between basic and clinical investigators from a wide range of disciplines including, Neurology, Neuroscience, Neurosurgery, Anesthesiology, Pharmacology, Biomedical Engineering, Computer Engineering, Instrumentation, Magnet Division, Medicine, Chemistry, and many others. Below is a description of the ongoing projects and the investigators involved. The facility was declared operational in October 2004 and more projects will be listed as capabilities come on line.
