1. Cerebral arterial pulsatility imaging using 4D flow MRI : methodological development and applications in brain aging
Abstract : 4D flow magnetic resonance imaging (MRI) is increasingly recognizedas a versatile tool to assess arterial and venous hemodynamics. Cerebral arterial pulsatility is typically assessed by analyzing flow waveforms over the cardiac cycle, where flow amplitude is a function of cardiac output, central arterial stiffness, and cerebrovascular resistance and compliance.

2. Microvascular disease in cognitive impairment
Abstract : Background: Cerebral small vessel disease has been recognized as the greatest vascular contributor to dementia. Previously, small vessel disease was thought to be part of normal aging. READ MORE

3. Modelling, Simulaltion, and Visualization of Deep Brain Stimulation
Abstract : Deep brain stimulation (DBS) is an effective surgical treatment for neurological diseases such as essential tremor, Parkinsonʹs disease (PD) and dystonia. DBS has so far been used in more than 70 000 patients with movement disorders, and is currently in trial for intractable Gilles de la Tourette’s syndrome, obsessive compulsive disorders, depression, and epilepsy.

4. Cardiovascular risk factor profiles in the development and progression of physical limitation in old age : a population-based study
Abstract : Preservation of independence has been reported to be highly desired by older adults, even more than longevity. However, subclinical cardiovascular pathology can threaten a healthy older adult’s maintenance of physical function. READ MORE

5. Developing a Porcine Model to Study the Glymphatic System
Abstract : The glymphatic system is a brain-wide solute clearance system that has developed in the brain to clear metabolic waste during sleep. This clearance is mediated by advective fluxes of cerebrospinal fluid (CSF) along perivascular spaces (PVS) and through the brain. READ MORE
