Bruker Events

Bruker BioSpin would like to invite you to the 2019 Bruker APAC preclinical MRI user meeting. This one-day user meeting is held in conjunction with the Brain 2019 Satellite Meeting (https://www.cnirbrain2019.com/ ) and features keynote talks by top preclinical MRI scientists from around the globe, including Prof Seong-Gi Kim, Prof Afonso Silva and Dr. Luisa Ciobanu(see biographies and topics below). Attendees who wish to share their research and learn from the experts are warmly welcome to present their work to a large audience. Do not miss out on this exciting opportunity to expand your research network and advance your scientific knowledge.

Keynote speakers

Dr. Luisa Ciobanu

Dr Luisa Ciobanu

Biography:

Dr. Luisa Ciobanu received her doctorate in Physics from The Ohio State University and has held research appointments at the University of Illinois at Urbana-Champaign and Pfizer, Inc. In 2007, she joined the staff of NeuroSpin at CEA-Saclay, where she now heads the NeuroPhysics team.

Topic:

Preclinical functional MRI at ultra-high magnetic fields

Despite the fact that BOLD-fMRI is routinely used to map brain activity and connectivity in preclinical and clinical settings, its exact relation with the underlying microscopic changes, either vascular or neuronal, is still not fully elucidated. The development of high magnetic fields promise substantial improvements in the contrast to noise ratio and the spatial resolution with which functional MRI maps are acquired possibly allowing the comparison with other, microscopic, techniques.

In the first part of the talk, Dr. Ciobanu will review the advantages, but also the challenges, imposed by imaging at ultra-high magnetic fields. Following this, Dr. Ciobanu will present recent results demonstrating that BOLD fMRI faithfully reports microvascular hyperemia, and that the detection of the smallest neuronal activation is limited only by its sensitivity.

Beside improved BOLD acquisitions, high magnetic fields allow the development of other alternative ways for studying neuronal activation. In the last part of her presentation, Dr. Ciobanu will describe a novel metabolic imaging approach, based on Chemical Exchange Saturation Transfer (CEST), for assessing the changes induced by neuronal stimulation in rat brains at 17.2T. Specifically, Dr. Ciobanu will present images acquired under glucose-sensitizing conditions showing a significant negative contrast that highlights the same brain regions as those activated in conventional BOLD maps.

 

 

Prof Afonso C. Silva

Prof Afonso C Silva

Biography:

Prof Afonso C. Silva received his Bachelor's Degree in Electrical Engineering from Universidade Federal de Pernambuco in Recife, Brazil, and his Ph.D. in Bioengineering from Carnegie Mellon University, where he worked on non-invasive MRI measurements of cerebral blood flow using the arterial spin labeling technique. He then went on to do post-doctoral training in the Center for Magnetic Resonance Research at the University of Minnesota, where he studied the temporal and spatial characteristics of functional brain hemodynamics under the supervision of Prof. Seong-Gi Kim. He joined NINDS as a Staff Scientist in 1999, and became an investigator in 2004. He moved to University of Pittsburg as Endowed Chair Full Professor of Neurobiology in 2018.

Topic: TBC

Prof Seong-Gi Kim

Prof. Seong Gi Kim

Biography:

Prof Seong-Gi Kim, Ph.D., is the Director of Neuroscience Imaging Research Center in the Institute of Basic Science (IBS), and professor of Biomedical Engineering in Sungkyunkwan Unviersity. He did his graduate works on in vivo NMR spectroscopy (1984-88) at Washington University, and postdoc training on structural biology at the University of Washington. In 1991, he moved to the Center for Magnetic Resonance Research in the University of Minnesota and was involved into the first human fMRI studies in 1992. He became full Professor before moving to the University of Pittsburgh in 2002. He was appointed inaugural Paul C. Lauterbur Chair in Imaging Research in 2009. Recently, he returned to Korea as the founding director of the Neuroscience Imaging Research Center. His major research focus is to develop magnetic resonance imaging techniques for measuring brain physiology and function, to determine relationships between neural activity and hemodynamic responses, and to apply imaging tools for answering neuroscience questions.

Topic:

Chemical Exchange-sensitive MRI: Saturation Transfer and Spin Locking

Many biomolecules have amide, amine, or hydroxyl protons that can exchange with water protons.  When the exchange rate is slower than the chemical shift difference between labile protons and water, its MR sensitivity can be dramatically enhanced by a chemical exchange-sensitive saturation transfer (CEST) or spin lock (CESL), which has been increasing used in many preclinical studies such as tumor, stroke, and muscle.  In this talk, Prof Kim will discuss principles, practical issues, recent technical developments, and in vivo applications.
