Open AccessAn evolution of low-field strength MRI
The paper describes the evolution of low-field MRI from the very early pioneering days in the late 70 s until today. It is not meant to give a comprehensive historical account of the development of MRI, but ra...

Open Access15 Years MR-encephalography
This review article gives an account of the development of the MR-encephalography (MREG) method, which started as a mere ‘Gedankenexperiment’ in 2005 and gradually developed into a method for ultrafast measure...

Open AccessThe variability of functional MRI brain signal increases in Alzheimer's disease at cardiorespiratory frequencies
Biomarkers sensitive to prodromal or early pathophysiological changes in Alzheimer’s disease (AD) symptoms could improve disease detection and enable timely interventions. Changes in brain hemodynamics may be ...

Volumetric analysis of MRI data monitoring the treatment of polycystic kidney disease in a mouse model
The human condition autosomal dominant polycystic kidney disease (ADPKD) is characterized by the growth of cysts in the kidneys that increase renal volume and lead to kidney failure. Mice studies are performed...

Joint Restoration of Bi-contrast MRI Data for Spatial Intensity Non-uniformities
The reconstruction of MRI data assumes a uniform radio-frequency field. However, in practice the radio-frequency field is inhomogeneous and leads to non-biological intensity non-uniformities across an image. T...

Trait anxiety and dynamic adjustments in conflict processing
Recently, it has been assumed that high- and low-trait-anxious subjects differ in the way they use fundamental cognitive control mechanisms. The present study was designed to further elucidate this topic by fo...

Analysis of MR Images of Mice in Preclinical Treatment Monitoring of Polycystic Kidney Disease
A common cause of kidney failure is autosomal dominant polycystic kidney disease (ADPKD). It is characterized by the growth of cysts in the kidneys and hence the growth of the entire kidneys with eventual fail...

Open AccessParallel imaging in non-bijective, curvilinear magnetic field gradients: a concept study
The paper presents a novel and more generalized concept for spatial encoding by non-unidirectional, non- bijective spatial encoding magnetic fields (SEMs). In combination with parallel local receiver coils the...

Quantitative diffusion tensor MR imaging of the brain: field strength related variance of apparent diffusion coefficient (ADC) and fractional anisotropy (FA) scalars
The objectives were to study the “impact” of the magnetic field strength on diffusion tensor imaging (DTI) metrics and also to determine whether magnetic-field-related differences in T2-relaxation times of bra...

Cardiac phase contrast gradient echo MRI: measurement of myocardial wall motion in healthy volunteers and patients
A number of methods have been proposed for the noninvasive measurement of myocardial wall motion. The paper describes a strategy for assessing myocardial motion based on the sensitivity of the phase of the MR-...

Visual Processing in Infants and Children Studied Using Functional MRI
We studied the development of visual processing in 58 children, ranging from 1 d to 12 y of age (median age 29 mo), using functional magnetic resonance imaging. All but nine children had either been sedated us...
