MR Spectroscopy and SWI: Neuropsyehological Outcome after Pediatric Brain Injury
… Magnetic Resonance Spectroscopy (MRS) and Susceptibility Weighted Imaging (SWI) when predicting long-term neurocognitive functioning in pediatric TBI patients. Twenty children/adolescents (mean age 13.3 years, 5.8 SD) treated at Loma Linda University Children's Hospital for a head injury …

Segmentation et extraction de caractéristiques des vaisseaux sanguins cérébraux à l'aide de l'IRM
… themselves. With the help of magnetic resonance imaging (MRI), it is possible to obtain images such as susceptibility weighted imaging (SWI) to see the veins or time-of-flight magnetic resonance angiography (TOF MRA) to visualize the arteries. These images allow having a structural representation …

Magnetic Resonance Imaging of Susceptibility Effects in Carotid Atherosclerosis
This thesis explores the use of susceptibility-weighted imaging (SWI) and quantitative susceptibility mapping (QSM), to characterize carotid artery plaques with and without the use of ultrasmall superparamagnetic iron oxide (USPIO) nanoparticle contrast agents. The overall hypothesis is that QSM …

Predicting learning success from patterns of pre-training magnetic resonance images
… of predicting learning from time-averaged T2*-weighted images, a follow-up experiment was designed and performed with additional magnetic resonance (MR) measurements, including susceptibility-sensitive ones, such as susceptibility-weighted imaging (SWI), T2-, T2*-quantitative as well as …

Imaging Iron Content In Patients With Multiple Sclerosis Using Magnetic Resonance Imaging
… sclerosis (MS), using in vivo magnetic resonance imaging. We first test the sensitivity and specificity of the MR method used, known as susceptibility weighted imaging (SWI) compared to other conventional MR techniques and rapid-scanning X-ray fluorescence in MS cadaver brains. Then, we use SWI …

Iron deficiency affects spatial learning in neonatal piglets
Iron deficiency is the most commonly reported nutritional deficiency in the world and has been linked to cognitive impairments in children. Our aim was to assess the impact of iron deficiency on cognition using neonatal piglets as a model for human infants, as neurodevelopment in piglets resembles …
