1. 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

2. Placental Function : An Epidemiological and Magnetic Resonance Study
Abstract : Placental function is central for normal pregnancy and in many of the major pregnancy disorders. We used magnetic resonance imaging techniques to investigate placental function in normal pregnancy, in early and late preeclampsia and in intrauterine growth restriction. READ MORE

3. Nuclear magnetic resonance and microcirculation: The influence of pulsatile brain-tissue motion on measurements of intravoxel incoherent motion and assessment of haemodynamics using exo- and endogenous tracers
Abstract : In this project, the potential of magnetic resonance (MR) imaging and spectroscopy in studies of microcirculation and haemodynamics was evaluated. The spatial and temporal characteristics of human pulsatile brain-tissue movements in healthy individuals, relevant for the understanding of the cerebrospinal-fluid (CSF) circulation and the pathogenesis of hydrocephalus, were thoroughly investigated.

4. Preeclampsia and the Brain : Epidemiological and Magnetic Resonance Studies
Abstract : Preeclampsia is a pregnancy specific syndrome that causes substantial maternal and fetal morbidity and mortality. One major contributor to maternal deaths is eclampsia, i.e. when seizures arise in the context of preeclampsia. READ MORE

5. Nuclear Magnetic Resonance for Diffusion Imaging Development and evaluation of spin-echo-based pulse sequences for in vivo studies of water self-diffusion
Abstract : The interest in diffusion imaging with nuclear magnetic resonance techniques has increased during the last few years. The main reason is the possibility of early diagnosis of acute ischaemic stroke, at a time when conventional MR techniques and computerised tomography fail. READ MORE
