Brain Oxygenation Monitoring during Cardiopulmonary Bypass by Near Infrared Spectroscopyn (Bashein, 1990), microembolism (Gallagher, 1973), and release of biocompatible materials. These factors can affect the intraoperative oxygen supply to the brain modifying the arterial oxygen saturation, the total and regional cerebral blood flow, and the hemoglobin (Hb) content.

Assessment of Local Brain Activationuring rest and during performance of a calculation task and a Stroop task..When a penetration depth of near-infrared light of 0.9 cm into the brain cortex was assumed, a statistically significant correlation between changes in CBF and changes in was found. These data confirm the validity of NIRS measurements in human adults.

Signal Sources in Bold Contrast FMRIuclear spins experience spatially varying magnetic fields, and consequently precess at different rates depending on position. The result is a loss of phase coherence within the voxel, and thus a decrease in signal relative to when the contrast agent is absent.

Correlation between Absolute Deoxyhaemoglobin Measured by Near Infrared Spectroscopy (NIRS) anure. Since alterations in tissue function normally precede structural damage, MR image contrast which accurately reflects this tissue function holds the promise of earlier detection of pathophysiology.
