Simultaneous recording of task-induced changes in blood oxygenation, volume, and flow using diffuse optical imaging and arterial spin-labeling MRIR D Hoge
Athinoula A Martinos Center for Biomedical Imaging, Massachusetts General Hospital, Building 149 13th Street, Charlestown, MA 02129, USA
Neuroimage 25:701-7. 2005..The ratio of fractional changes in oxidative metabolism to fractional change in blood flow was found to be 0.56 +/- 0.08, in general agreement with previous studies of flow-metabolism coupling...
A temporal comparison of BOLD, ASL, and NIRS hemodynamic responses to motor stimuli in adult humansT J Huppert
Harvard Medical School Graduate Program in Biophysics, Massachusetts General Hospital, Charlestown, MA 02129, USA
Neuroimage 29:368-82. 2006..The observed co-variance in these parameters between subjects is in agreement with hemodynamic models and provides further support that fMRI and NIRS have similar vascular sensitivity...
BOLD signal responses to controlled hypercapnia in human spinal cordJ Cohen-Adad
Unité de Neuroimagerie Fonctionnelle, Centre de Recherche, Institut Universitaire de Geriatrie de Montreal, Department of Physiology, Universite de Montreal, Montreal, Canada
Neuroimage 50:1074-84. 2010..Finely, we believe that the use of controlled global stimuli, such as hypercapnia, will help assess the effectiveness of new acquisition techniques...
Can the cerebral metabolic rate of oxygen be estimated with near-infrared spectroscopy?D A Boas
Athinoula A Martinos Center for Biomedical Imaging, Massachusetts General Hospital, Harvard Medical School, Charlestown, MA 02129, USA
Phys Med Biol 48:2405-18. 2003..A more precise estimate of the flow-consumption ratio will require better estimates of the model parameters or flow information, as can be provided by combining NIRS with fMRI...
Oxidative metabolism and the detection of neuronal activation via imagingR D Hoge
Nuclear Magnetic Resonance Center, Massachusetts General Hospital, Charlestown, MA, USA
J Chem Neuroanat 22:43-52. 2001....
Comparison of physiological noise at 1.5 T, 3 T and 7 T and optimization of fMRI acquisition parametersC Triantafyllou
MGH MIT HMS A A Martinos Center for Biomedical Imaging, Massachusetts General Hospital, Department of Radiology, Charlestown, 02129, USA

In vivo DTI of the healthy and injured cat spinal cord at high spatial and angular resolutionJ Cohen-Adad
Groupe de Recherche sur le Système Nerveux Central, Department of Physiology, Faculty of Medicine, Universite de Montreal, Montreal, QC, Canada
Neuroimage 40:685-97. 2008..Important outcomes of this work are (i) tractography-based localisation of anatomical tracts in the thoraco-lumbar spinal cord and (ii) in vivo assessment of axonal integrity following experimental spinal cord injury...
