  1. 16. Proton Relaxation Properties of a Particulate Iron Oxide MR Contrast Agent in Different Tissue Systems : Implications for Imaging

    Författare :Atle Bjørnerud; Graham A. Wright; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Iron oxide nanoparticles; USPIO; NC100150 Injection; water exchange limited relaxation; MR perfusion imaging.; Onkologi; Oncology; Onkologi; radiologi; Radiology;

    Sammanfattning : Knowledge of the relationship between in vivo contrast agent concentration and magnetic resonance (MR) signal response is an important requirement in contrast enhanced MR imaging in general and in MR based perfusion imaging in particular. This relationship is a complex function of the properties of the contrast agent as well as the structure of the target tissue. LÄS MER

  3. 17. Investigation of nanoparticle-cell interactions for development of next generation of biocompatible MRI contrast agents

    Författare :Natalia Abrikossova; Kajsa Uvdal; Caroline Brommesson; Eva Särndahl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Progress in synthesis technologies and advances in fundamental understanding of materials with low dimensionality has led to the birth of a new scientific field, nanoscience, and to strong expectations of multiple applications of nanomaterials. The physical properties of small particles are unique, bridging the gap between atoms and molecules, on one side, and bulk materials on the other side. LÄS MER
