For example, in order to realistically model regeneration of liver after intoxication or partial hepatectomy, quantification of cell proliferation and cell death is needed (Hoehme et al. 2007, 2010).
Conversely with the Southampton method of quantification, partial volume factors are already accounted for, which can be seen by the much smaller differences in calibrated and non-calibrated values (Figs. 1 and 2).
As is the case for any clinical test, Aβ imaging does not represent a perfect tool and some justified concerns remain, such as the nonspecific white matter retention or the effects of atrophy and partial volume on quantification.
Such a NCT partial volume voxel water quantification technique has been developed at The Pennsylvania State University Radiation Science and Engineering Center RSECC).
We conclude by briefly touching on available and developing technologies for quantitative root phenotyping from lab to field, from quantification of partial root profiles in the field to 3D reconstruction of whole root systems.
The AIF is also directly linked to most of the major sources of artefacts in CBF quantification, including partial volume effect, bolus delay and dispersion, peak truncation effects, contrast agent non-linearity, etc.
Improvements in PET/CT quantification include partial volume corrections methods to overcome limitations in PET spatial resolution, most commonly through sharpening of small image features with a point spread or imaging system response function[32].
Quantification of partial and complete transformation in all three parasite populations revealed that at day 29 almost all puf2 sporozoites had transformed, whereas only a minor fraction of WT and puf1 sporozoites exhibited signs of premature transformation (Figure 6B).
Analysis of 33.3 Mb sequence data resulted in quantification and partial sequence reconstruction of major repeat families occurring in the pea genome with at least thousands of copies.
Validations of the analytical methods on urine (with and without enzymatic degradation) were also performed (full validation for glucuronides determination, partial validation for diosmetin quantification upon enzymatic digestion; data presented in Table 4).> Differential ion-mobility mass spectrometry (DMS) was finally used for the confirmation of 3- O-Gluc as major metabolite excreted in urine.
