To assess in clinical practice arterial blood volume flow (BVF) from ultrasound measurements, the assumption is commonly made that the velocity profile can be approximated by a quasi-static Poiseuille model. However, pulsatile flow behaviour is more accurately described by a Womersley model. No clinical studies have addressed the consequences on the(More)
INTRODUCTION Vascular access (VA) surgery, a prerequisite for hemodialysis treatment of end-stage renal-disease (ESRD) patients, is hampered by complication rates, which are frequently related to flow enhancement. To assist in VA surgery planning, a patient-specific computer model for postoperative flow enhancement was developed. The purpose of this study(More)
The surgical creation of a vascular access, used for hemodialysis treatment of renal patients, has considerable complication rates (30–50 %). Image-based computational modeling might assist the surgeon in planning by enhanced analysis of preoperative hemodynamics, and in the future might serve as platform for outcome prediction. The objective of this study(More)
Non-invasive imaging is currently applied in diagnosing and monitoring of abdominal aortic aneurysms. However, the quality of the images and especially the visibility of the vessel wall are not optimal for wall stress analysis of or strain imaging. In this study, enhancement of the aortic wall by compounding of different images was investigated. In healthy(More)
PURPOSE To evaluate the accuracy and precision of manual and automatic blood vessel diameter measurements, a quantitative comparison was conducted, using both phantom and clinical 3D magnetic resonance angiography (MRA) data. Since diameters are often manually measured, which likely is influenced by operator dependency, automatic lumen delineation, based on(More)
PURPOSE The aim of this work was to establish the relationship between traditional blood vessel mapping for vascular access (VA) creation by B-mode ultrasound (US) and novel non contrast-enhanced magnetic resonance angiography 
(NCE-MRA), and to study the potential influence of the diameter assessment technique on the choice of hemodialysis vascular access.(More)
