Arterial stiffness, Blood Pressure and Cardiac output study; ABC-study;A Prospective, Multidisciplinary study of arterial stiffness measures in patients treated for aortic aneurysms in relation to blood pressure and cardiac output

Zie document PROTOCOL SYNOPSIS ABC study

The use of Rienso, an ultrasmall superparamagnetic particle of iron-oxide, as a MRI contrast agent to image inflammation in the atherosclerotic plaque.

In the current study, we want to demonstrate Rienso uptake in the vessel wall in patients with cardiovascular disease and relate the uptake of Rienso to endothelial permeability.

Study to identify the genetic variations associated with phantom limb pain

The primary goals of this study are to: i. Identify genetic variations responsible for PLP across the whole genomeMore than 90% of SNPs are found in introns or intergenic regions and most of them are probably of little functional consequence.…

Silent MR Angiography (MRA) of intracranial and extracranial carotid arteries.

Test the optimized MRI sequences/technology against CTA as gold standard, in terms ofimage quality, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), speed, and accuracy/reproducibility of extracted quantitative parameters.

Optimalization of a new 3 tesla Magnetic Resonance Imaging protocol to visualize the aorta

optimization of a new 3 Tesla Magnetic Resonance Imaging protocol for imaging of the aortic vessel wall in order to enhance the identification of individuals at highest risk of developing clinically manifest atherosclerosis

A reproducibility study of novel noninvasive multimodal imaging techniques in atherosclerosis in healthy and cardiovascular diseased subjects

Primary Objectives:A. To assess the reproducibility and variability (interscan, intra- and interreader) of novel (DCE-)MRI techniques to measure vessel wall dimensions, wall shear stress and vessel wall permeability in healthy and cardiovascular…
