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.
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
To examine the hour-to-hour and day-to-day reproducibility of the CAV-test in young and older humans
The main objective of this study is to assess the prevalence cardiovascular disease and the prevalence of risk factors for cardiovascular disease in patients with gout, and to quantify the risk for cardiovascular disease in patients with gout. The…
Determining the role of duplex ultrasound in patients with a clinical suspicion for temporal arteritis.Determing the sensitivity, specificity, negative predictive value and positive predictive value of duplex ultrasound in patients with a clinical…
Frequency of PNH in a selection of patients with DVT. In several publications PNH has been described especially in patients with DVT and younger than 30 years of age and/or with DVT on unusual places.
Goal of our study is to compare the CO measuments by the Oesophageal Doppler Monitor (ODM, Cardio Q) with the TPTD technique (PiCCO) and to determine reliability of the ODM in absolute CO values and as a trend monitor. A validation study comparing…
The main objective is to show whether imaging characteristics assessed at baseline can predict clinical events in patients with a 30-69 % symptomatic carotid stenosis.

* To determine the minimum effective dose of 5-aminolevulinic acid (Gliolan) for adequate MitoPO2 measurements during upper endoscopy.
A study to explore three different diagnostic tools (predictors) (tcPO2 measurement, BOLD MRI and DCE MRI) quantifying the degree of tissue perfusion and oxygenation at the intended amputation level in patients with refractory critical limb ischemia…
- To elucidate whether simultaneous measurement of brachial BP may improve the accuracy of assessment of interarm BP differences compared with sequential interarm BP assessment
To determine FDG uptake following uncomplicated EVAR using the Nellix endoprosthesis. Does uncomplicated EVAR using the Nellix endoprosthesis result in increased FDG uptake and false positive PET imaging? .
Validation of CT angiography and MRI protocols to identify the different components of the atherosclerotic plaque in the carotid arteries compared to and histology.
The aim of this study is to perform a head-to-head comparison between SPECT/CT and PET/CT in comparison with conventional catheter-based coronary angiography and FFR measurements, to establish the diagnostic value of the modern cardiac myocardial…
