The presence of unpaired electrons in deoxyhemoglobin and hemosiderin gives them paramagnetic properties which produce a nonuniform magnetic field and a rapid dephasing of proton spins, resulting in a loss of signal best seen on SWI.
It is possible to separately quantify the relative amounts of the reduced and oxidized forms of hemoglobin or cytochrome oxidase by using two measurement wavelengths (typically 760-780 nm for deoxyhemoglobin and 825-850 nm for oxyhemoglobin) at which the two forms have different absorption coefficients.
3 Hemoglobin loaded to capacity with oxygen is called deoxyhemoglobin.
This study also involved collecting x-ray data and refining the structure of natural deoxyhemoglobin using the same protocol as that used for the variant.
Near-infrared rays of dual wavelengths (760 nm, 840 nm) are radiated to living body tissue from two light sources in a probe, absorbed by both oxyhemoglobin (oxyHb) and deoxyhemoglobin (deoxyHb), and returned to the detector site in the probe.
They determine the ratio of oxyhemoglobin to deoxyhemoglobin by measuring absorbance at 660 and 940 nm several times per second.
Aurum's T2* Oxygen Challenge (OC) MRI imaging technique is based on conversion of deoxyhemoglobin to oxyhemoglobin, a change made possible by Oxycyte's ability to provide oxygen into areas otherwise inaccessible to red blood cells.
Background: Blood oxygenation level-dependent magnetic resonance imaging (BOLD-MRI) is a functional MRI technique which involves using the paramagnetic properties of deoxyhemoglobin to image the local tissue oxygen concentration.

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.
