    The Center for Reproducible Neuroimaging Computation seeks to implement a shift in the way neuroimaging research is performed and reported. Through the development and implementation of a FAIR (Findable, Accessible, Interoperable and Reusable, Wilkinson et al., 2016) technology stack that supports a comprehensive set of data management, analysis, and utilization frameworks in support of both basic research and clinical activities, our overarching goal is to improve the reproducibility of neuroimaging science and extend the value of our national investment in neuroimaging research. Reproducibility is critical because the current literature is fraught with published results that are due to mistakes or turn out to be false positive (contributed to by the lack of statistical power). More importantly, given the current publication system, it is exceedingly difficult to discern between false positive and true positive finding as data is hard to aggregate, and exact methods are hard to replicate.

    This Center will develop, investigate, and disseminate new hyperpolarized MR techniques, new 13C agents and specialized analysis open-source software for data reconstruction and interpretation. The Technology Research +amp; Development projects will leverage the extensive DNP facilities and experience of the project leaders to develop improved, robust hyperpolarized MRI methods. These technology developments will be driven by Collaborative Projects led by outstanding clinical and basic scientists who aim to use hyperpolarized 13C MRI to accomplish the scientific goals of their funded research. These technical developments will also be disseminated to the Service Project investigators for extramural feedback and then widely to the scientific community via a dedicated website and onsite training. This center will provide state-of-the-art training in this new metabolic imaging field and sponsor a yearly symposium focused on hyperpolarized MR technology development.

    The MIT Laser Biomedical Research Center (LBRC) develops the basic scientific understanding and new techniques required for advancing the clinical applications of lasers and spectroscopy. To fulfill the significant and ever growing need for a more comprehensive and potentially non-invasive understanding of the human body, the LBRC merges optical spectroscopy, imaging, scattering, and interferometry techniques. Specifically, researchers at the LBRC study the biophysics and biochemistry of healthy and diseased biological structures from the subcellular to the entire-organ scale. For example, spectral diagnosis instruments based on near-infrared Raman scattering, intrinsic fluorescence, diffuse reflectance, and single light scattering provide complementary data on human disease. Combining these techniques into a single, multimodal instrument is applied for diagnostics in various organs, including cervix, oral cavity, Barrett's esophagus, artery, breast, skin, as well as for transcutaneous measurements of blood constituents. The LBRC has been and continues to be a pioneer in the field of developing novel optical probes for use under direct visualization or with endoscopes and biopsy devices.Similarly, new microscopy tools based on interferometry are designed and exploited for measuring cellular structures and their dynamics. In particular, these techniques provide the crucial and unique ability to non-invasively study cells in their native states at remarkably high spatial and temporal resolutions. Using these novel microscopy tools, the LBRC has conducted critical studies to elucidate the fundamental biology of diseases as diverse as malaria and multiple myeloma, and physiological processes such as cell growth and cell division. The interferometry concepts have also been vital in Center’s research efforts to develop optical tools for deep-tissue imaging while minimizing the adverse effects of light scattering or diffusion. Furthermore, the unique and powerful combination of the interferometric microscopy and vibrational spectroscopy tools adds a hitherto unexplored dimension to optical sensing by simultaneous probing of morphological and chemical information.A unique feature of the LBRC is its ability to form strong clinical collaborations with outside investigators in areas of common interest that further the Center's mandated research objectives. A major focus of these collaborations is to rapidly translate the novel photonic technologies introduced at the LBRC into the clinic and potentially into the field. Another focal point of the collaborations is to enable external researchers to exploit laser-based techniques for medical applications such as the spectral diagnosis of disease, investigation of biophysical and biochemical properties of cells and tissues, and development of novel imaging techniques.

    The Harvard/MIT Center for Magnetic Resonance (CMR) is a joint effort between Harvard Medical School and the Massachussetts Institute of Technology. The CMR core research program is focused on the development and applicaton of new magnetic resonance technologies directed at structural biology using a cluster of high field solution and solid state NMR spectrometers. Investigations includes studies of membrane proteins, translation initiation, and amyloid fibrils associated with several diseases. Membrane proteins are examined in nanodiscs using solution NMR and in lipsomes and 2D crystals using magic angle spinning (MAS) dipolar recoupling techniques. Translation initiation is investigated with solution NMR. MAS is the method of choice for experiments on amyloid fibrils since they are both insoluble and do not diffract to high resolution. The CMR is also heavily involved in the development of new software and instrumentation for magnetic resonance. These include methods for non uniform sampling (NUS) to enable efficient acquisiton of higher dimensional NMR spectra and high frequency microwave technology (~150-600 GHz) is being developed for both DNP-NMR and EPR experiments at high magnetic fields. Recent DNP experiments have yielded significant signal enhancments from membrane and amyloid protein samples and enabled experiments that are otherwise not possible. The CMR has pioneered the development of low temperature MAS technology. In addition, there is an extensive effort focused on the creation of new pulse sequences for performing assignments and determining structures in both solution and MAS experiments. Finally, the staff at the CMR interact extensively with outside investigators.

    The Southwestern NMR Center for In Vivo Metabolism exists to develop and apply new methods for analysis of metabolic networks in intact tissues, animals and human patients. The importance of understanding abnormal metabolism in common diseases such as cancer, diabetes and heart disease has long been appreciated. Because of constraints in technology, however, much of this research has been conducted in isolated systems where clinical relevance may be uncertain. Progress in magnetic resonance technology provides a foundation for major advances towards new ways of imaging metabolism in patients. These new techniques offer the advantage of imaging biochemical pathways without radiation. The focus of this Resource is to bring these technologies to a level where clinical research is feasible through the development of new MR contrast agents, NMR spectroscopy at high fields, and imaging of hyperpolarized 13C.

    The Columbia University Radiological Research Accelerator Facility (RARAF) is a dedicated facility for radiobiological research with available ionizing radiations such as protons, alpha particles, and neutrons. RARAF is well-established and highly user-friendly. The focus of RARAF is the development of high-throughput single-cell/single-particle microbeams, which can deliver defined amounts of ionizing radiation into individual cells with a spatial resolution of a few microns or better. The ability of a microbeam to put double strand break damage at any specific known location in a given cell has allowed new approaches to the study of damage signaling.
