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. Non-invasive imaging for improved cardiovascular diagnostics : Shear wave elastography, relative pressure estimation, and tomographic reconstruction
Abstract : Throughout the last century, medical imaging has come to revolutionise the way we diagnose disease, and is today an indispensable part of virtually any clinical practice. In cardiovascular care imaging is extensively utilised, and the development of novel techniques promises refined diagnostic abilities: ultrasound elastography allows for constitutive tissue assessment, 4D flow magnetic resonance imaging (MRI) enables full-field flow mapping, and micro-Computed Tomography (CT) permits high-resolution imaging at pre-clinical level.

3. Imaging the tumor microenvironment : the dynamics and modification of hypoxia
Abstract : The tumor vasculature is poor and heterogeneous which may result in inadequate oxygenation and changed energy status. In addition the balance between cell proliferation and the rate of cell death is disturbed, which results in tumor growth. READ MORE

4. Juxtarenal aortic aneurysm - Endovascular treatment and imaging techniques
Abstract : Treatment of abdominal aortic aneurysms has shifted rapidly from open surgery to minimally invasive endovascular aneurysm repair (EVAR). However, anatomical limitations such as short or absent proximal sealing neck and poor access vessels exclude up to 50% of patients. READ MORE

5. Imaging of hip trauma - occult, suspect and concomitant fractures
Abstract : Background: Between one and nine percent of all hip fractures are occult or suspect and further examinations with computed tomography (CT) and/or magnetic resonance imaging (MRI) are vital for further handling. Statistically robust conclusions have not been previously reported. READ MORE
