PURPOSE To assess the reproducibility and the distribution of intravoxel incoherent motion (IVIM) and diffusion-tensor (DT) imaging parameters in healthy renal cortex and medulla at baseline and after hydration or furosemide challenges. MATERIALS AND METHODS Using an institutional review board-approved HIPAA-compliant protocol with written informed(More)
RATIONALE AND OBJECTIVES To evaluate intra- and inter-observer variability of right ventricular (RV) functional parameters as evaluated by cardiac magnetic resonance imaging (MRI) in patients with acquired heart disease (AHD), and to identify factors associated with an increased variability. MATERIALS AND METHODS Sixty consecutive patients were enrolled.(More)
Two new recommendations of the European Society of Radiology task force and the European Society of Uroradiology workgroup on paediatric uroradiology are presented. One deals with diagnostic imaging in children after trauma to the urinary tract-renal trauma, in particular. The other concerns the evaluation of suspected renal hypertension. Available data in(More)
PURPOSE To investigate whether variability in reported renal apparent diffusion coefficient (ADC) values in literature can be explained by the use of different diffusion weightings (b values) and the use of a monoexponential model to calculate ADC. MATERIALS AND METHODS This prospective study was approved by institutional review board and was(More)
The ESPR Uroradiology Task Force and the ESUR Paediatric Working Group present two new recommendations on imaging in childhood cystic kidney disease and in childhood renal transplantation, and address the presently restricted availability of contrast-enhanced (ce) US in children. New insights into the genetics require an updated classification of paediatric(More)
Auto-immune immunoglobulin-lipoprotein complexes (Ig-Lp), as well as other modified lipoproteins, are activators of the transformation of macrophages into foam cells which may be the first step in atherogenesis. In humans circulating Ig-Lp have been demonstrated in autoimmune hyper- or dyslipidemia (AIH, DIH) and found to be associated with conditions(More)
In autoimmune hyper- or dislipidemia secondary to a monoclonal antilipoprotein gammapathy, immunoglobulin-lipoprotein (Ig-Lp) complexes are found in the circulating blood. In order to determine their possible significance in common types of hyperlipidemia we compared the Ig-Lp content of sera from 98 healthy blood donors and 155 outpatients from a Lipid(More)
MR urography (MRU) is an emerging technique particularly useful in paediatric uroradiology. The most common indication is the investigation of hydronephrosis. Combined static and dynamic contrast-enhanced MRU (DCE-MRU) provides both morphological and functional information in a single examination. However, specific post-processing must be performed and to(More)
MR urography (MRU) has been widely accepted as a substitute to intravenous urography for investigating children with a dilated urinary tract after preliminary assessment by US and voiding cystourethrography. Hydronephrosis is by far the main indication for MRU because upper tract dilatation is a frequent condition in infants and children. Recent advances in(More)
PURPOSE To assess prospectively the ability of quantitative low-dose three-dimensional magnetic resonance (MR) renography to help identify the cause of acute graft dysfunction. MATERIALS AND METHODS This HIPAA-compliant study was approved by the institutional review board, and written informed consent was obtained. Between December 2001 and May 2009,(More)
