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 reticulocyte count and the curve of the absorption spectrum of oxyhemoglobin and deoxyhemoglobin were within the reference interval.
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.
In the deoxyhemoglobin form, hemoglobin A is soluble yielding a clear solution, while hemoglobin S polymerizes becoming insoluble producing turbidity.
Hence, regional cerebral increases in deoxyhemoglobin will cause decreases in the MR signal for the region.
Active neurons convert oxyhemoglobin to deoxyhemoglobin as they use up oxygen, and these two molecules can be distinguished using MRI.
Spectroscopic signals can be analyzed using mathematical models to calculate functional parameters and concentrations of biochemical components, such as oxy- and deoxyhemoglobin, water and fat content.
That means that the ratio between oxyhemoglobin (molecule that transfers oxygen) and deoxyhemoglobin (molecule that transfers carbon dioxide) in that particular area changes.
