2], lie in the contributions of other skin chromophores, variations in blood vessel location and density, variation in spectral signatures of oxy- and deoxyhemoglobin in the NIR regime, and changes in vessel diameter and subsequent optical pathlength during pulsation.
Because the required optical penetration depths are considerably lower, shorter wavelength light can be used, eliminating much of the variation between oxy and deoxyhemoglobin.
Spectrophotometry of hemoglobin: absorption spectra of bovine oxyhemoglobin, deoxyhemoglobin, carboxyhemoglobin, and methemoglobin.
Chemically cross-linking either the [beta] or [alpha] chains stabilizes the more rigid structure of deoxyhemoglobin normally maintained by salt bridges and 2,3-DPG, with the net effect of decreasing [O.
These methods are based on the MR detection of both cerebral blood flow effects as well as small shifts in the relative amounts of oxyhemoglobin vs deoxyhemoglobin in the vascular bed.
2]-Hb), deoxyhemoglobin (deoxy-Hb), and carboxyhemoglobin (CO-Hb).
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.
