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>
Insulin-stimulated glucose uptake in skeletal muscle, adipose tissue and liver: A positron emission tomography study
<p>Objective: Insulin resistance is reflected by the rates of reduced glucose uptake (GU) into the key insulin-sensitive tissues, skeletal muscle, liver and adipose tissue. It is unclear whether insulin resistance occurs ...
Assessment of myocardial viability with [15O]water PET: A validation study in experimental myocardial infarction
<p>Background: Assessment of myocardial viability is often needed in patients with chest pain and reduced ejection fraction. We evaluated the performance of reduced resting MBF, perfusable tissue fraction (PTF), and ...
Type 2 diabetes enhances arterial uptake of choline in atherosclerotic mice: an imaging study with positron emission tomography tracer F-18-fluoromethylcholine
<p><b>Background: </b>Diabetes is a risk factor for atherosclerosis associated with oxidative stress, inflammation and cell proliferation. The purpose of this study was to evaluate arterial choline uptake and its relationship ...
Bone Marrow Metabolism Is Impaired in Insulin Resistance and Improves After Exercise Training
<p><strong>Context: </strong>Exercise training improves bone mineral density, but little is known about the effects of training on bone marrow (BM) metabolism. BM insulin sensitivity has been suggested to play an important ...
Effects of dipeptidyl peptidase 4 inhibition on inflammation in atherosclerosis: A 18F-fluorodeoxyglucose study of a mouse model of atherosclerosis and type 2 diabetes
<p><strong>Background and aims: </strong>Dipeptidyl peptidase 4 (DPP-4) inhibitors have anti-inflammatory and atheroprotective effects. We evaluated the effects of the DPP-4 inhibitor linagliptin on atherosclerotic plaque ...

Novel Effects of the Gastrointestinal Hormone Secretin on Cardiac Metabolism and Renal Function
<p>The cardiac benefits of gastrointestinal hormones have been of interest in recent years. The aim of this study was to explore the myocardial and renal effects of the gastrointestinal hormone secretin in the GUTBAT trial (NCT03290846). A placebo-controlled crossover study was conducted on 15 healthy males in fasting conditions, where subjects were blinded to the intervention. Myocardial glucose uptake was measured with [<sup>18</sup>F]2-fluoro-2-deoxy-D-glucose ([<sup>18</sup>F]FDG) positron emission tomography. Kidney function was measured with [<sup>18</sup>F]FDG renal clearance and estimated glomerular filtration rate (eGFR). Secretin increased myocardial glucose uptake compared to placebo (secretin vs. placebo, mean + standard deviation, 15.5 ± 7.4 vs. 9.7 ± 4.9 μmol/100g/min, 95% confidence interval (CI) [2.2, 9.4], p=0.004). Secretin also increased [<sup>18</sup>F]FDG renal clearance (44.5 ± 5.4 vs. 39.5 ± 8.5 ml/min, 95%CI[1.9, 8.1], p=0.004) and eGFR was significantly increased from baseline after secretin, compared to placebo (17.8 ± 9.8 vs. 6.0 ± 5.2 Δml/min/1.73m<sup>2</sup>, 95%CI[6.0, 17.6], p=0.001). Our results implicate that secretin increases heart work and renal filtration, making it an interesting drug candidate for future studies in heart and kidney failure.</p>...
Prosthetic Valve Candida Endocarditis: A Case Report with 18F-FDG-PET/CT as Part of the Diagnostic Workup
Diagnosis of <i>Candida</i> spp. infective endocarditis (IE) is challenging, and diagnostic delays are common. We describe two patients with <i>Candida</i> spp. prosthetic valve endocarditis (PVE) and <sup>18</sup>fluoro ...
Amyloid-Targeting PET Tracer [18F]Flutemetamol Accumulates in Atherosclerotic Plaques
<p>Atherosclerosis is characterized by the accumulation of oxidized lipids in the artery wall, which triggers an inflammatory response. Oxidized low-density lipoprotein (ox-LDL) presents amyloid-like structural properties, ...
