21. Assessment of myocardial viability using magnetic resonance imaging
Abstract : Myocardial infarction (MI) following an acute coronary occlusion is a leading cause of morbidity and mortality. During revascularization, microemboli may complicate treatment and affect cardiac function. The long-term effects of microembolization are not fully elucidated. READ MORE

22. Separation of Water and Fat Signal in Magnetic Resonance Imaging : Advances in Methods Based on Chemical Shift
Abstract : Magnetic resonance imaging (MRI) is one of the most important diagnostic tools of modern healthcare. The signal in medical MRI predominantly originates from water and fat molecules. READ MORE

23. Magnetic Resonance Imaging in Parkinsons's disease and related disoders
Abstract : Objectives: To identify diagnostic and prognostic biomarkers in the cerebral white (WM) and the deep grey matter (GM) in patients with Parkinson’s disease (PD) and atypical parkinsonian syndromes (APS) using magnetic resonance imaging (MRI). Methods: Patients with a clinical diagnosis of PD, multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) were included in the study. READ MORE

24. Functional Magnetic Resonance Imaging for Clinical Diagnosis : Exploring and Improving the Examination Chain
Abstract : Functional Magnetic Resonance Imaging (fMRI) is a relatively new imaging technique, first reported in 1992, which enables mapping of brain functions with high spatial resolution. Functionally active areas are distinguished by a small signal increase mediated by changes in local blood oxygenation in response to neural activity. READ MORE

25. Degradation, Metabolism and Relaxation Properties of Iron Oxide Particles for Magnetic Resonance Imaging
Abstract : Whereas the effect of size and coating material on the pharmacokinetics and biodistribution of iron oxide based contrast agents are well documented, the effect of these parameters on liver metabolism has never been investigated. The primary purpose of this work was to evaluate the effect of iron oxide particle size and coating on the rate of liver clearance and particle degradation using a rat model. READ MORE
