Graphical analysis of PET data applied to reversible and irreversible tracers.
431
TL;DR: In this paper, the authors apply graphical analysis to both reversible and irreversibly binding tracers in order to provide insight into the binding kinetics of tracer kinetics in a visual way, and some problems encountered in separating tracer delivery and binding are considered.

Wavelet denoising in voxel-based parametric estimation of small animal PET images: a systematic evaluation of spatial constraints and noise reduction algorithms
Yi Su,Kooresh I. Shoghi +1 more
TL;DR: Noise reduction techniques combined with SCWNLS methods provide more accurate parameter estimation than with either of the two techniques alone and would be useful for cardiac, neurological and oncologic applications.
Positron emission tomography imaging of dopamine D2 receptors using a highly selective radiolabeled D2 receptor partial agonist
Jinbin Xu,Suwanna Vangveravong,Shihong Li,Jinda Fan,Lynne Jones,Jinquan Cui,Ruike Wang,Zhude Tu,Wenhua Chu,Joel S. Perlmutter,Robert H. Mach +10 more
TL;DR: Challenge studies indicate that there is a significant displacement of [(11)C]SV-III-130 by d-Amphetamine-induced increases in synaptic dopamine levels, a measure of D2 receptor binding in vivo, in the caudate and putamen.

Interactive versus additive relationships between regional cortical thinning and amyloid burden in predicting clinical decline in mild AD and MCI individuals.

TL;DR: It is shown that regions outside the MTL may be more vulnerable and specific to AD dementia, suggesting that lower cortical thickness values in specific regions, vulnerable to amyloid pathology, predict clinical decline already at the prodromal stage.

An automated method for delineating a reference region using masked volumewise principal-component analysis in 11C-PIB PET.
TL;DR: A fast and automated method to delineate the reference region of images obtained from an N-methyl-11C-2-(4′-methylaminophenyl)-6-hydroxy-benzothiazole 11C-PIB PET study on Alzheimer disease patients and healthy controls using a newly introduced masked volumewise principal-component analysis is introduced.

Graphical Evaluation of Blood-to-Brain Transfer Constants from Multiple-Time Uptake Data:
TL;DR: A theoretical model of blood–brain exchange is developed and a procedure is derived that can be used for graphing multiple-time tissue uptake data and determining whether a unidirectional transfer process was dominant during part or all of the experimental period.
Graphical Evaluation of Blood-to-Brain Transfer Constants from Multiple-Time Uptake Data. Generalizations:
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.

Distribution Volume Ratios without Blood Sampling from Graphical Analysis of PET Data
Jean Logan,Joanna S. Fowler,Nora D. Volkow,Nora D. Volkow,Gene-Jack Wang,Yu-Shin Ding,David Alexoff +6 more
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.

Graphical analysis of reversible radioligand binding from time-activity measurements applied to [N-11C-methyl]-(-)-cocaine PET studies in human subjects

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.
