BACKGROUND: Compartmental analysis is a standard method to quantify metabolic processes using fluorodeoxyglucose-positron emission tomography (FDG-PET). For liver studies, this analysis is complex due to the hepatocyte capability to dephosphorylate and release glucose and FDG into the blood. Moreover, a tracer is supplied to the liver by both...
Background and Aims: 18F Natrium Fluoride (NaF) has been proposed as a clinical tool to identify and quantify ongoing arterial calcification. Estimation of NaF uptake by vessel walls is feasible in the majority of large vessels; it is conversely more challenging within the coronary tree, given the small size of these vessels and the artifacts...
Myocardial perfusion and ischemia scores obtained from myocardial perfusion scintigraphy (MPS) have strong independent prognostic value in elderly individuals without known coronary artery disease (CAD). Herein we aimed to assess their independent diagnostic value and accuracy for CAD while considering different thresholds of myocardial ischemia.
Several studies have highlighted the role of vascular (18)F-NaF uptake as a marker of ongoing calcium deposition. However, accumulation of (18)F-NaF is often inconsistent with localization of arterial plaque. Calcification activity and thus (18)F-NaF uptake might prevail in the earlier plaque stages. To test this hypothesis, we evaluated...
Mechanisms of hematopoietic reconstitution after bone marrow (BM) transplantation remain largely unknown. We applied a computational quantification software application to hybrid 18F-fluorodeoxyglucose positron emission tomography (PET)/computed tomography (CT) images to assess activity and distribution of the hematopoietic system throughout...
