Background Myocardial T2* relaxometry at 1.5T provides reliable non-invasive assessment of cardiac iron burden and is commonly used for the diagnosis and monitoring of patients at risk. 3T CMR offers some advantages over 1.5T but iron assessment has not been routinely performed at 3T due to technical concerns regarding artefacts and rapid signal loss, as well as a lack of tissue calibration. In...
Introduction RGD peptidomimetics conjugated to Inand Y-DOTA complexes, and to Gd-DTPA complex, have been recently developed to target the αvβ3 receptor. In this work, we describe the grafting of a new RGD peptidomimetic on ultrasmall particles of iron oxide (USPIO) coated with 3,3’-bis(phosphonate)propionic acid in the context of magnetic resonance molecular imaging.The grafting rates have been...
Introduction: Restless leg syndrome (RLS) is a sensory-motor disorder characterized by uncontrollable urges to move the legs, causing chronic sleep disturbances. Brain iron deficiency has been considered as an important contributing factor to RLS [1-2]. In this study, we applied voxel-based relaxometry (VBR) for in vivo iron measurement and voxel-based morphometry (VBM) for morphological study ...
