The ISMAR Prize sponsored by Cambridge Isotope Laboratories The International Society of Magnetic Resonance awards a prize every three years for outstanding achievement in the field of magnetic resonance. Seiji Ogawa is the winner of the 2007 ISMAR Prize. The presentation will be made at the ISMAR Conference in Taiwan on October 2007. Ogawa is widely recognized for his seminal contributions to NMR, particularly his discovery in 1990 of the BOLD [Blood Oxygenation Level Dependent] contrast method that has revolutionized medical imaging as both a research and clinical tool. He used the magnetic susceptibility difference between oxyhemoglobin and deoxyhemoglobin in the blood to demonstrate contrast in NMR signals from the brain as the blood feeds active neurons. Functional MRI (fMRI) using BOLD is now employed as the principal technique to map the visual, auditory and sensory regions for research in neurobiology and psychology. It is used in surgical planning to identify the motor cortex. Previous winners: 2004 - Richard E. Norberg & Irving J. Lowe 2001 - Jean JEENER 1998 - Ray FREEMAN 1995 - Alfred G.
