Biologic variability and dramatic changes of brain development in children aged 0 to 2 years make it challenging to accurately detect subtle abnormalities in single Magnetic Resonance Imaging (MRI) scans. Diffusion MRI (dMRI) indices such as Apparent Diffu ...
Magnetic resonance imaging (MRI) is one of the most powerful diagnostic techniques used in clinics. The need for higher spatial resoln. and better sensitivity led to the development of imagers working at high magnetic fields. The routine clin. use of 3 T M ...
Modeling of flow in intracranial aneurysms (IAs) requires flow information at the model boundaries. In absence of patient-specific measurements, typical or modeled boundary conditions (BCs) are often used. This study investigates the effects of modeled ver ...
Breast cancer is the most common, and the number one cause of death by cancer among women. However, when it is sufficiently early detected, heavy treatments can be avoided, and morbidity and mortality can be reduced. This is the reason why randomized clini ...
The purpose of this study was to evaluate a new polymer-based and magnetic resonance (MR) imaging-compatible guide wire for its application in MR-guided endovascular interventions, particularly for interventional peripheral MR angiography in swine experime ...
Little is known about the significance of hospitals as point sources for emission of organic micropollutants into the aquatic environment. A mass flow analysis of pharmaceuticals and diagnostics used in hospitals was performed on the site of a representati ...
Computerised gamma-ray emission tomography has been applied to single PWR UO2 fuel rods, with pellet averaged burnups of 52, 71, 91 and 126 GWd/t respectively, for the determination of 134Cs, 137Cs and 154Eu internal radial distributions. State-of-the-art ...
Currently trainees typically learn surgery techniques directly on mocks, animals or cadavers. For safety, cost and ethics reasons, one cannot try all possible strategies to achieve efficient learning. Virtual Reality (VR) based surgery training systems int ...
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 ...
A novel MR-guided brain therapy device operating at 1 MHz has been designed and constructed. The system has been installed and tested in a clinical 1.5 T Philips Achieva MRI. Skull bone distortions induced on the ultrasonic beam are corrected using the con ...
