16] After cerebral vessel occlusion, different concentrations of paramagnetic deoxyhemoglobin between ischemic and normal brain area can be detected on SWI as asymmetric prominent hypointense vessels.
We could not perform group statistical analyses on the data for muscle deoxyhemoglobin signals due to considerable between-subjects and within-subjects variability in the complexity of the signals from the NIRS unit.
In brain areas where a task activates neurons, blood flow is altered such that more oxyhemoglobin is present compared to deoxyhemoglobin.
Sickle cell disease (SCD) is an inherited hematologic disorder caused by the intraerythrocytic polymerization of deoxyhemoglobin S, which deforms the shape of red blood cells and alters their ability to circulate, particularly in narrow vascular beds.
Nitrite reduction to nitric oxide by deoxyhemoglobin vasodilates the human circulation," Nature Medicine, vol.
172) Without the oxygen attached, the oxyhemoglobin becomes deoxyhemoglobin, fMRI takes advantage of the "fact that oxyhemoglobin is not magnetic but deoxyhemoglobin is magnetic.
Diffuse axonal injury-related brain lesions are mainly hemorrhagic which are well recognized by this technique (7), (8) In the acute and subacute phase of hemorrhagic lesions, the existence of paramagnetic materials such as methemoglobin, deoxyhemoglobin, hemosiderin, generates signal intensity in T2GE (9) while in spin echo imaging selective T2 relaxation enhancement of deoxyhemoglobin is related to time varying magnetic field (10).
The AVOXimeter 4000 whole-blood oximeter is capable of multiple-band spectro-photometric analysis, which allows the researcher to quickly determine the oxyhemoglobin, deoxyhemoglobin, methemoglobin, and carboxyhemoglobin percentage and total hemoglobin (derived/calculated) in a whole blood sample.
For a detailed explanation of the mechanics of the hemodynamic response, and, accordingly, the blood-oxygenation level dependent (BOLD) response, including the ratio of oxygenated hemoglobin to deoxyhemoglobin, see BUXTON, supra note 7; HUETTEL ET AL.
Changes in the concentrations of oxy- and deoxyhemoglobin were monitored and energy consumption, or activation of the brain region during the performance of cognitive tasks were analyzed.
