Magnetic Resonance Imaging (MRI)

ARA-MBI’s preclinical imaging facility houses a state-of-the-art Bruker Biospec 9.4 Tesla MRI. This flagship instrument includes two cryogenically cooled (20 - 30 K) coils for mouse and rat brain imaging that give up to 3x the signal-to-noise of standard coils for unsurpassed image clarity. Room temperature coils include anatomically shaped receive-only coils for neurological and cardiac imaging in mice and rats as well as transmit and receive volume coils with internal diameters ranging from 23 mm to 86 mm. The system is also fitted with a broadband RF channel for arterial spin labeling and X-nuclei measurements and a dual-tuned volume resonator with internal diameter of 40 mm is available for 1H/23NA imaging.

Magnetic Particle Imaging (MPI)

MPI is a technique that detects the magnetic properties of superparamagnetic iron-oxide (SPIO) nanoparticles to produce 3D images. This gives the ability to monitor nanoparticles in cells, blood, and other systems. The system at ARA-MBI is also equipped with CT and HYPER capabilities. HYPER allows control of hyperthermia to a small region of interest in the sample. Heating can be controlled from mild to extreme, and can be used to promote apoptosis, immunogenesis, and drug delivery applications.

Positron Emission Tomography (PET) / X-Ray Computed Tomography (CT)

ARA-MBI’s preclinical imaging facility includes a Mediso Nano PET/CT instrument for high resolution scanning of small animals. The instrument provides a high-precision gantry for exact alignment of PET/CT data and with a gantry bore opening of 16 cm can accommodate imaging of mice, rats and rabbits. A complete 360° PET detector ring consisting of 12 modules provides ultra high resolution and sensitivity, with the reconstructed resolution in the centre of the field of view being less than 1.0 mm.
PET and/or CT scanning can extend up to 300 mm in the axial direction by automated translation of the bed for whole body imaging, with a transaxial range of 45-125 mm. Real time reconstruction of CT data can achieve voxel sizes in the range of 13-37 um. Low dose CT protocols (<50 mGy for a 3 minute scan) are compatible with longitudinal rodent studies.

Fluorescence Emission Computed Tomography (FLECT)

The BioFLECT instrument located in ARA-MBI’s preclinical imaging facility offers uniform sensitivity and approximately 1 mm resolution throughout the subject. The system includes the most commonly used laser/filer combinations and has a transaxial field of view (FOV) of 38 mm and an axial FOV of 100 mm (mice).
