1. PET and MR imaging in prostate cancer
Abstract : The current risk assessment of prostate cancer (PC) relies on histopathological samples from biopsies and clinical variables such as prostate-specific antigen (PSA). However, this comes with uncertainties and in some cases it can be challenging to separate patients who would benefit from radical treatment and those who would not. READ MORE

2. Biophysical modelling in diffusion MRI: The role of tissue microstructure and water exchange
Abstract : Diffusion MRI is widely used to study brain structure in vivo. While this technique is often applied to investigations of brain connectivity, it can also be used to infer specific information about the tissue microstructure; for example, to estimate the axon diameter. READ MORE

3. Ions in models of articular cartilage : The importance of electrostatic interactions for transport and equilibrium distribution
Abstract : Osteoarthritis (OA) is a degenerative disease that affects articular cartilage, which covers the surfaces of the bones in synovial joints. At later stages the disease can result in major loss of articular cartilage and thus lead to major disability. READ MORE

5. Radiotherapy Gel Dosimetry: Development and Application of Normoxic Polymer Gels
Abstract : In many radiotherapy applications, true three-dimensional dosimetry with good spatial resolution that can be achieved in a single measurement would be of great value. Polymer gel dosimetry fulfils many of the demands on such a system. In this study, methods to facilitate the implementation of gel dosimetry have been investigated. READ MORE
