1. WAVELET NOISE REDUCTION AND VASCULAR WATER TRANSPORT MODELLING : APPLICATIONS TO DIFFUSION AND PERFUSION MRI
Abstract : Magnetic resonance imaging (MRI) is a powerful medical imaging technique, used to detect and characterise a range of diseases and conditions. It is based on the use of a strong static magnetic field in combination with magnetic field gradients and pulsed radiofrequency electromagnetic fields to visualise various organs and structures in the body according to their morphology or function.

2. On potentials and limitations of perfusion MRI in neurological disorders
Abstract : Cerebral perfusion outlines several parameters which describe the status of cerebral haemodynamics. Numerous neurological diseases affect cerebral perfusion, thus the importance of diagnostic measurements. READ MORE

3. Short- and long-term consequences of sport-related concussion
Abstract : Concussions are common in contact sports. Symptoms such as confusion and/or loss of consciousness following an impact to the head indicate that a sport-related concussion (SRC) has occurred. The symptoms normally resolve within 10-14 days following an SRC in adults although at least 10 % of athletes suffer from prolonged symptoms. READ MORE

4. MRI Perfusion Measurements using Magnetic Susceptibility Effects: : Calibration Approaches and Contrast Agent Quantification
Abstract : Exchange of oxygen and nutrients between blood and tissue occurs at the capillary level of the blood system. The blood volume flow rate in the capillaries is often referred to as perfusion, and knowledge about perfusion provides important information about the function and viability of the tissue, for example, in patients with ischaemic stroke, cancer, and neurodegenerative diseases.

5. When I show the Beatles then you say: ‛Ramones!’ : imaging semantic memory in Alzheimer’s disease and semantic dementia
Abstract : Elderly people contacting the health care system because of suspected dementia very often report word forgetfulness, a clinical condition referred as anomia, often one of the first signs of cognitive decline. Considering the complexity of human language it is no wonder that dementia disorders can affect language processing, which in its turn relies heavily on the intactness of the semantic memory system.
