Validation of quantitative [F]NaF PET uptake parameters in bone diseases: a systematic review.
Ann Nucl Med

Purpose: [F]NaF PET has become an increasingly important tool in clinical practice toward understanding and evaluating diseases and conditions in which bone metabolism is disrupted. Full kinetic analysis using nonlinear regression (NLR) with a two-tissue compartment model to determine the net rate of influx (K) of [F]NaF is considered the gold standard for quantification of [F]NaF uptake. However, dynamic scanning often is impractical in a clinical setting, leading to the development of simplified semi-quantitative parameters.

The detection and assessment of atherosclerosis and cardiovascular calcification can inform risk stratification and therapies to reduce cardiovascular morbidity and mortality. In this review, we provide an overview of current and emerging imaging techniques for assessing atherosclerosis and cardiovascular calcification in animal models. Traditional imaging modalities, such as computed tomography (CT) and magnetic resonance imaging (MRI), offer non-invasive approaches of visualizing atherosclerotic calcification in vivo; integration of these techniques with positron emission tomography (PET) imaging adds molecular imaging capabilities, such as detection of metabolically active microcalcifications with F-sodium fluoride.

Objective: The study aimed to explore the role of fluorine-18-aluminum fluoride-1,4,7-triazacyclononane-1,4,7-triacetic acid-octreotide (F-OC) positron emission tomography/computed tomography (PET/CT) in neuroblastoma (NB) and compared it with Iodine-123 labeled metaiodobenzylguanidine (I-MIBG) scintigraphy with single photon emission computed tomography/computed tomography (SPECT/CT), as well as to investigate the feasibility of the modified Curie scoring system and International Society of Pediatric Oncology Europe Neuroblastoma (SIOPEN) skeleton scoring system applied in F-OC PET/CT.
Methods: Patients with pathologically confirmed NB underwent I-MIBG scintigraphy with SPECT/CT and F-OC PET/CT according the standard imaging protocols. The interval between the two imaging techniques ranged from 0 to 22 days (median interval: 9 days).
Estimating inflammatory risk in atherosclerotic cardiovascular disease: plaque over plasma?
Eur Heart J Cardiovasc Imaging

Department of Vascular Medicine, Amsterdam UMC, University of Amsterdam, Amsterdam, the Netherlands.
Inflammation is an important driver of disease in the context of atherosclerosis, and several landmark trials have shown that targeting inflammatory pathways can reduce cardiovascular event rates. However, the high cost and potentially serious adverse effects of anti-inflammatory therapies necessitate more precise patient selection. Traditional biomarkers of inflammation, such as high-sensitivity C-reactive protein (hsCRP), show an association with cardiovascular risk on a population level, but do not have specificity for local plaque inflammation.
