This thesis focuses on intracranial aneurysms and particularly on the effect of blood flow in the three major phases that characterize an aneurysm: initiation, growth and rupture. As it stands today, blood flow is the major driver of this disease. The unde ...
Ability to peer into human body is an essential diagnostic tool in medicine. Out of the four major imaging modalities that include ultra-sound, magnetic resonance imaging (MRI), and positron emission tomography (PET), nuclear medicine is gaining more wides ...
Drug eluting stents (DES) have been successfully implemented in clinical practice in the treatment against coronary artery disease. Compared to the implantation of bare metal stents, restenosis rates decreased significantly after stenting of DES into coron ...

Interventional radiologists manipulate guidewires and catheters and steer stents through the patient’s vascular system under X-ray imaging for treatment of vascular diseases. The complexity of these procedures makes trainingmandatory in order to master han ...
This paper presents the results of the Virtual Intracranial Stenting Challenge (VISC) 2007, an international initiative whose aim was to establish the reproducibility of state-of-the-art haemodynamical simulation techniques in subject-specific stented mode ...
Low wall shear stress (WSS) increases neointimal hyperplasia (NH) in vein grafts and stents. We studied the causal relationship between WSS and NH formation in stents by locally increasing WSS with a flow divider (Anti-Restenotic Diffuser, Endoart SA) plac ...
Drug-eluting stents are cardiovascular stents able to release a medical drug after implantation. The medical drug is, in general, aimed at healing the vascular tissues injured after implantation and to prevent restenosis. In spite of their apparent simplic ...

Coherent synchrotron sources open the way to powerful new radiology approaches. We briefly review the conceptual background of such approaches, then we present some examples of applications with particular emphasis on materials-science systems. ...
