" /> spectroscopy, near-infrared - CISMeF





Preferred Label : spectroscopy, near-infrared;

MeSH definition : A noninvasive technique that uses the differential absorption properties of hemoglobin and myoglobin to evaluate tissue oxygenation and indirectly can measure regional hemodynamics and blood flow. Near-infrared light (NIR) can propagate through tissues and at particular wavelengths is differentially absorbed by oxygenated vs. deoxygenated forms of hemoglobin and myoglobin. Illumination of intact tissue with NIR allows qualitative assessment of changes in the tissue concentration of these molecules. The analysis is also used to determine body composition.;

MeSH synonym : spectrometries, near-infrared; spectroscopy, nir; spectrometry, near infrared; near-infrared spectroscopy; near-infrared spectroscopies; near-infrared spectrometries; spectroscopies, near-infrared; nir spectroscopy; nir spectroscopies; spectroscopies, nir; spectrometry, near-infrared; near-infrared spectrometry; spectroscopy, near infrared;

MeSH annotation : a type of spectrum anal; DF: note short X ref; usually NIM;
