Chapter
Comparison of Cerebral Blood Volume Measured by Near Infrared Spectroscopy and Contrast Enhanced Magnetic Resonance Imaging
Cerebral blood volume (CBV) can be quantified by both near infrared spectroscopy (NIRS) and magnetic resonance imaging (MRI). The aim is to compare CBV results obtained by NIRS and MRI in adult patients.

Chapter
Comparison of Absolute Cerebral Haemoglobin Concentration in Neonates Measured Directly and by the Oxygen Swing Method both Based on Near Infrared Spectrophotometry
The total cerebral haemoglobin concentration (tHb in μmol/1) as a major indicator of the oxygen transport capacity is investigated in neonates. Two methods to determine tHb by near infrared spectrophotometry (...

Chapter
Measurement of Absolute Cerebral Haemoglobin Concentration in Adults and Neonates
The concentration and saturation of the main oxygen carrier of the blood—the haemoglobin—may be an important clinical factor to judge the oxygenation of tissue. The brain is very sensitive to under-oxygenation...

Chapter
Estimation of Cerebral Blood Volume and Transit Time in Neonates From Quick Oxygen Increases Measured by Near-Infrared Spectrophotometry
Quick oxygen increases are used to estimate the cerebral blood flow (cbf) or cerebral haemoglobin flow (cHbf) in neonates by near infrared spectrophotometry (NIRS) (Edwards et al, Skov et al., Bucher et al.). ...
