Zie document PROTOCOL SYNOPSIS ABC study

Characterization of ascending aortic flow patterns and vessel wall in patients with aortic valve stenosis before and after surgical valve replacement: a 4D Flow Magnetic Resonance Imaging study.

We aim to i) describe flow patterns and flow-related dynamics in the ascending aorta of patients with aortic valve stenosis, ii) compare these flow parameters before and after surgical aortic valve replacement and iii) compare flow parameters with…

Imaging of extracranial carotid aneurysms

The primary objective of this study is to observe if there are differences in diameter measurements of 3T MRI and CTA at baseline and 1 year after baseline measured by two independent observers (radiologist) blinded for previous imaging. The…
