Accuracy and precision of MR blood oximetry based on the long paramagnetic cylinder approximation of large vessels.

30 Jul 2009 An accurate noninvasive method to measure the hemoglobin oxygen saturation (%HbO(2)) of deep-lying vessels without catheterization would have many clinical applications. Quantitative MRI may be the only imaging modality that can address this ... Read more...

A New EPR oximetry protocol to estimate the tissue oxygen consumption in vivo.

30 Jul 2009 Abstract The oxygen consumption rate in tumors affects tumor oxygenation and response to therapies. A new EPR method was developed to measure tissue oxygen consumption non-invasively. The protocol was based on the measurement of pO(2) during a ... Read more...

Oxygen sensitivity and biocompatibility of an implantable paramagnetic probe for repeated measurements of tissue oxygenation.

30 Jul 2009 The use of oxygen-sensing water-insoluble paramagnetic probes, such as lithium octa-n-butoxynaphthalocyanine (LiNc-BuO), enables repeated measurements of pO(2) from the same location in tissue by electron paramagnetic resonance (EPR) spectroscopy. ... Read more...

Technical information about 'Oximetry'

Definition: The determination of oxygen-hemoglobin saturation of blood either by withdrawing a sample and passing it through a classical photoelectric oximeter or by electrodes attached to some translucent part of the body like finger, earlobe, or skin fold. It includes non-invasive oxygen monitoring by pulse oximetry.
