Graphical analysis of PET data applied to reversible and irreversible tracers.

TL;DR: 3D matrices that can hold cells and enhance cell survival while improving long-term blood vessel growth to supply the cells are bioengineered and revealed that specialized T-cell therapy could prevent kidney transplant rejection without the need for toxic drugs.

TL;DR: This work demonstrates that the trade-off between sensitivity and spatial resolution in PET can be improved thanks to coded aperture collimators and statistical reconstruction algorithm; it also provides new tools to implement such improvements.

TL;DR: The agreement between fetal striatal DVRs using maternal arterial blood and maternal and fetal cerebellum as input functions strongly supports the hypothesis that the conditions necessary for graphical analysis have been met.

TL;DR: A new approach based on Richardson-Lucy algorithm based on a normal inverse Gaussian distribution model in shearlet domain was incorporated to the approach as a regularization step to provide an accurate quantification parameters with an efficient intensity recovery and noise reduction.

TL;DR: General equations are derived that can be used to analyze tissue uptake data when the blood–plasma concentration of the test substance cannot be easily measured and for situations when trapping of theTest substance is incomplete and for a combination of these two conditions.

TL;DR: In this paper, the authors proposed a graphical method for determining the distribution volume ratio (DVR), which is a linear function of receptor availability, which does not require blood sampling and is widely used as a model parameter in imaging studies.

TL;DR: It can be shown that, for many systems, linearity is effectively reached some time before this, and this method provides an easy, rapid method for comparison of the reproducibility of repeated measures in a single subject, for longitudinal or drug intervention protocols, or for comparing experimental results between subjects.

TL;DR: An infusion protocol consisting of bolus plus continuous infusion of CF was designed and applied and has the potential to shorten scan time and simplify the acquisition and processing of scan and blood data.
