My research career focuses on improvement of endovascular image guided interventions and encompasses three major components: vascular disease research, endovascular device development and medical imaging. Since the beginning of my research I tried to develop and test endovascular device in patient relevant physiology in a lab setting. I developed the first balloon deployable asymmetric flow diverters nearly eight years ago and test them in idealized aneurysms phantoms. Over the years with my collaborators at Toshiba Stroke and Vascular Research Center (TSVRC), I developed an entire chain of manufacturing and testing of such devices. Concerning imaging, my research is focused on physiological conditions determination based on imaging such as angiography and CT and micro-CT.

Department chair Kenneth Pearsen, MD, is a seasoned hospital-based radiologist and educator. He has lived and worked in Western New York for the past 25 years. He earned his undergraduate degree from the University of Pennsylvania and his medical degree from the Columbia University College of Physicians and Surgeons. He did his medical residency in diagnostic radiology at Massachusetts General Hospital, where he also completed a fellowship in neuroradiology and is board-certified by the American Board of Radiology and the American Board of Neuroradiology, with added qualifications in vascular and interventional radiology and neuroradiology. In addition, he is president of the UBMD Radiology practice plan, co-founder and former president and chief executive officer of Great Lakes Medical Imaging (GLMI), serves as radiology chief of service for Kaleida Health and chief of radiology at Buffalo General Medical Center. Before founding GLMI, he was president of Ide Radiology Group in Rochester, where he also was clinical assistant professor of radiology at the University of Rochester Medical Center and chief of radiology at Highland Hospital. Michael E. Cain, MD, vice president for health sciences and dean of the Jacobs School of Medicine and Biomedical Sciences said “Dr. Pearsen has the administrative, scientific, clinical, leadership and visionary skills needed to move the Department of Radiology forward.”

Magnetic resonance imaging (MRI) is a unique technique for studying the human body since it is non-invasive, does not require ionizing radiation and offers a multiplicity of complementary tissue contrasts. My research seeks to explore the potential of MRI for clinical and pre-clinical imaging and to provide new and improved MRI technology. The goal of this endeavor is twofold: 1.) to contribute deeper insight into the etiology, pathogenesis and potential treatment of neurodegenerative diseases, and 2.) to give clinicians the ability to diagnose diseases earlier and monitor them more accurately. I am currently focusing on understanding MRI contrast mechanisms as well as on developing innovative imaging and reconstruction techniques that improve the sensitivity and specificity of MRI with respect to biophysical properties of brain tissue. Advancements in this field promise to have a substantial impact on our understanding of biophysical and morphological tissue alterations associated with neurological diseases and their treatment. We recently pioneered quantitative susceptibility mapping (QSM), a breakthrough in quantitative MRI. This technique allows for unique assessment of endogenous and exogenous magnetic particles in the human brain such as iron, calcium, myelin or contrast agents. The concept of QSM is fundamentally different from conventional MRI techniques as it involves solving for all imaging voxels simultaneously in large physically motivated equations, a so-called inverse problem. At the Buffalo Neuroimaging Analysis Center (BNAC), we use QSM to explore whether brain iron may serve as an early biomarker for diseases of the central nervous system such as multiple sclerosis and Parkinson’s disease. Other interesting applications of this technique we are investigating include differentiation between hemorrhages and calcifications, detection of demyelination and quantification of tissue oxygenation. I am fascinated by the synergies from combining physical expertise with high-level mathematical, numerical and engineering concepts to advance our understanding of the human brain. Consequently, my research activities are generally interdisciplinary and involve collaboration with clinicians, physicists, computer scientists, technicians and engineers. Student projects typically focus either on the application of techniques or on technical developments. Undergraduate, graduate and doctoral candidates from a variety of disciplines such as neuroscience, physics and mathematics work collaboratively in my lab.

I direct the Buffalo Neuroimaging Analysis Center (BNAC) and have established the center as a world leader in performing quantitative MRI analysis in neurodegenerative disorders. I also direct the Translational Imaging Center at UB’s Clinical Translational Research Center (CTRC). I strive to extend the boundaries of current knowledge about neurological diseases and disorders through innovative imaging research techniques and the application of bioinformatics resources. My efforts are directed toward advancing technical, basic and translational research at UB which will, in turn, advance patient care. I have secured more than $30 million in research grants for collaborative research projects involving UB investigators as well as national and international collaborators. My research interests include structural and functional quantitative MRI analysis for humans and animals, including lesion/tumor identification and segmentation; perfusion and dynamic contrast-enhanced (DCE) mapping and quantification; fluid flow quantification; functional MRI analysis; diffusion tensor reconstruction and tractography; voxel-wise mapping and image-based group statistical analysis; longitudinal change analysis and tissue/pathology/structure volumetry. I study the application of these techniques in healthy individuals and in patients with various disease states such as multiple sclerosis (MS), stroke, Alzheimer’s disease, Parkinson’s disease, epilepsy, systemic lupus erythematosus and traumatic brain injury. I also concentrate on therapeutic interventions, including therapy directed toward assessing neuroprotective efforts in neurodegenerative disorders as well as the venous function, genetic and neuroepidemiology fields of these diseases. I direct the neurology resident research program. Over a period of two years, I guide third- and fourth-year medical residents through a rigorous assigned scientific research project that is a critical, required part of their training. In addition, I mentor and supervise undergraduate, master’s and doctoral students and MRI fellows. In this role, I help to educate these trainees on clinical MRI use as well as neuroimaging analysis. I also oversee students and fellows conducting research in neurological disorders. One of the most rewarding experiences in my career is helping young physicians and researchers start successful clinical or research careers.
