The metabolic syndrome (MetS) is characterized by ectopic lipid accumulation. Magnetic resonance (MR) imaging and spectroscopy can quantify ectopic lipid accumulation. Consequences of MetS can be evaluated with MR on a whole-body level. In the liver, several techniques are used to quantify hepatic steatosis and differentiate stages of nonalcoholic fatty(More)
OBJECTIVE To assess the feasibility of renal proton magnetic resonance spectroscopy for quantification of triglyceride content and to compare spectral quality and reproducibility without and with respiratory motion compensation in vivo. MATERIALS AND METHODS The Institutional Review Board of our institution approved the study protocol, and written(More)
INTRODUCTION Dietary restriction benefits health and increases lifespan in several species. Food odorants restrain the beneficial effects of dietary restriction in Drosophila melanogaster. We hypothesized that the presence of visual and odorous food stimuli during a prolonged fast modifies the neuroendocrine and metabolic response to fasting in humans. (More)
OBJECTIVES The aim of this study was to compare bright blood high spatial resolution (HR) coronary magnetic resonance angiography (MRA) with low spatial resolution (LR) bright blood coronary MRA at 7 T. MATERIALS AND METHODS Twenty-four healthy volunteers underwent navigator-gated 3-dimensional imaging of the right coronary artery at 7 T using 2(More)
Computed tomography is a noninvasive imaging modality that can be used for the evaluation of cardiac structure and function. This review provides an overview of established and emerging applications of cardiac computed tomography, including evaluation of left and right ventricular function, ventricular morphology, native and prosthetic valves, and pulmonary(More)
OBJECTIVE The aim of this study was to determine whether high permittivity (HP) pads can be used to increase the signal-to-noise ratio (SNR) of cardiac proton magnetic resonance spectroscopy at 3 T, allowing faster data acquisition. MATERIALS AND METHODS The institutional review board approved the study protocol, and written informed consent was obtained(More)
