The Animal Magnetic Resonance Imaging (MRI) Core specializes in cardiovascular imaging of mice and rats. We perform all aspects of imaging studies from planning to data analysis and interpretation. We work with investigators to tailor imaging studies to individual study needs. Cardiac function and anatomy, stress testing and vascular imaging are examples of studies performed in the Core; we perform a variety of studies in addition to cardiac imaging. A full list follows. The Core staff facilitates implementation of imaging studies for investigators and teaches interested investigators and fellows. The Core can also incorporate additional imaging modalities through the MIF, such as computed tomography (CT), ultrasound and bioluminescence. Studies are performed in the NIH Mouse Imaging Facility (MIF).
Although the Core is primarily concerned with projects related to cardiovascular imaging in rodents, the team has also worked on more specialized applications, particularly in high resolution microimaging.
