Purpose In this article, we discuss dynamic whole-body (DWB) positron emission
tomography (PET) as an imaging tool with significant clinical potential, in relation to …

Spatial resolution is an important metric for performance characterization in PET systems.
Measuring spatial resolution is straightforward with a linear reconstruction algorithm, such …

Segmentation, denoising, and partial volume correction (PVC) are three major processes in
the quantification of uptake regions in post-reconstruction PET images. These problems are …

This study aimed to assess coronary microvascular dysfunction (CMD) differences in
hypertrophic cardiomyopathy (HCM) patients using cardiac magnetic resonance (CMR) first …

Background Preclinical and human positron emission tomography studies have produced
inconsistent results regarding the effects of opioids on mesolimbic dopamine (DA). Here, we …

Parametric images for dynamic positron emission tomography (PET) are typically generated
by an indirect method, ie reconstructing a time series of emission images, then fitting a …

Background Currently, there is no established non-invasive imaging approach to directly
evaluate myocardial microcirculatory function in order to diagnose microvascular disease …

In myocardial perfusion imaging with dynamic positron emission tomography (PET), direct
parametric reconstruction from the projection data allows accurate modeling of the Poisson …

Myocardial perfusion imaging using CT (MPI-CT) has the potential to provide quantitative
measures of myocardial blood flow (MBF) which can aid the diagnosis of coronary artery …

Although coronary microvascular disease is now a well-recognized entity that is associated
with significant morbidity and mortality, current non-invasive strategies cannot differentiate …
