Magnetic Resonance Imaging and Near Infrared Spectroscopy

Researcher: Vladislav Toronov

Continuous wave broadband near infrared spectroscopy (NIRS) is a promising technology for functional brain imaging which measures hemodynamic signals from the brain, similar to those of functional magnetic resonance imaging (fMRI). Given the limitations of each of the two techniques, simultaneous application of NIRS and MRI can help to better understand blood-oxygen-level-dependent (BOLD) effect in normal and diseased brains. Physiological information resulting from the optical modality in combination with magnetic resonance signal has a potential for enhancement of the diagnostic power of imaging for cerebrovascular reactivity conditions (e.g., steno-occlusive disorders).
