First-in-Human Study of 68 Ga-DOTA-Siglec-9, PET Ligand Targeting Vascular Adhesion Protein 1
Sialic acid-binding immunoglubulin-like lectin 9 (Siglec-9) is a ligand of vascular adhesion protein 1 (VAP-1). A gallium 68-labeled peptide of Siglec-9, <sup>68</sup>Ga-DOTA-Siglec-9, holds promise as a novel PET tracer ...
Seasonal variation in the brain μ-opioid receptor availability
<p>Seasonal rhythms influence emotion and sociability. The brain μ-opioid receptor (MOR) system modulates a multitude of seasonally varying socioemotional functions, but its seasonal variation remains elusive with no ...
Exercise training decreases pancreatic fat content and improves beta cell function regardless of baseline glucose tolerance: a randomised controlled trial
<p>Aims/hypothesis: Pancreatic fat accumulation may contribute to the development of beta cell dysfunction. Exercise training improves whole-body insulin sensitivity, but its effects on pancreatic fat content and beta cell ...
Human Brown Fat Radiodensity Indicates Underlying Tissue Composition and Systemic Metabolic Health
Context: Metabolic imaging studying brown adipose tissue (BAT) physiology has increased, in which computed tomography (CT) is commonly used as an anatomical reference for metabolic positron emission tomography (PET) imaging. ...
Artificial Intelligence to Improve Risk Prediction with Nuclear Cardiac Studies
<p>Purpose of Review<br>As machine learning-based artificial intelligence (AI) continues to revolutionize the way in which we analyze data, the field of nuclear cardiology provides fertile ground for the implementation of ...
Global and segmental absolute stress myocardial blood flow in prediction of cardiac events: [15O] water positron emission tomography study
Purpose We evaluated the value of reduced global and segmental absolute stress myocardial blood flow (sMBF) quantified by [O-15] water positron emission tomography (PET) for predicting cardiac events in patients with ...
18-kDa translocator protein ligand 18F-FEMPA: Biodistribution and uptake into atherosclerotic plaques in mice
<p>18F-FEMPA shows rapid blood clearance and uptake in the mouse aorta. Uptake in atherosclerotic plaques correlated with the amount of macrophages, but did not exceed that in the normal vessel wall.<br /></p>
Evaluation of [68Ga]Ga-DOTA-TCTP-1 for the Detection of Metalloproteinase 2/9 Expression in Mouse Atherosclerotic Plaques
Background: The expression of matrix metalloproteinases 2/9 (MMP-2/9) has been implicated in arterial remodeling and inflammation in atherosclerosis. We evaluated a gallium-68 labeled peptide for the detection of MMP-2/9 ...
One-tissue compartment model for myocardial perfusion quantification with N-13 ammonia PET provides matching results: A cross-comparison between Carimas, FlowQuant, and PMOD
<p>Purpose To cross-compare three software packages (SPs)-Carimas, FlowQuant, and PMOD-to quantify myocardial perfusion at global, regional, and segmental levels. Materials and Methods Stress N-13 ammonia PET scans of 48 ...
