An Imaging Biomaker can be defined as a single quantitative unit acquired by an imaging modality and expressing morphology or function of a cell, tissue or organ, which objectively measured and evaluated as a prognostic indicator of normal, physiological and pathogenic processes.
Accurate conversion of magnetic resonance spectra to quantitative units of concentration generally requires compensation for differences in coil loading conditions, the gains of the various receiver amplifiers, and rescaling that occurs during post-processing manipulations.
Calibration of the raw X-ray fluorescence data to quantitative units of this type is done by using measurements of standards of known composition and relating the measured fluorescence peak areas to the peak areas of the standard.
However, for a variety of reasons (e.g. Kane & O' Neill, 1998), electrode responses in vivo may not be the same ex vivo, and in the present study O2 signals are described in arbitrary rather than quantitative units.
Thereafter, a semi-quantitative, unit-less index of microcirculatory resistance can be calculated [ 26].
Of further relevance, quantitative single unit electromyography data has demonstrated the presence of small, normal and enlarged motor units in patients with spinal muscular atrophy, further supporting mixed pathology comprising axonal degeneration and regeneration (Galea et al., 2001).
Morgan Stanley's write-down occurred on its proprietary trading desk, which suffered a $480 million loss over the summer in its quantitative trading unit.
