This program involves multimodal imaging techniques that use magnetic resonance imaging (MRI) as either a base or as a complimentary technique. Multimodal imaging combines information from two or more imaging modalities such as MRI, computed tomography (CT), positron emission tomography (PET), and ultrasound (US). These combined techniques such as PET-MR or MR-US have unique challenges when developing quantitative imaging protocols.

In addition, the program has a focus on techniques that challenge the current methodology of MRI. Techniques such as dynamic nuclear polarization which allow for enhanced signals useable to track metabolite conversion in the body are of interest. NIST is also working on low-field spectroscopy and ultra-low field MRI as alternatives to high-field MRI.

NIST has an in-house variable field preclinical scanner and access to other clinical scanners in the Boulder and Denver area. These projects involve working with collaborators from academic institutions, professional societies (ISMRM, RSNA), and possibly other federal agencies to develop the calibration structures and quantitative imaging protocols.
