Abstract: Abstract A dual T1-T2 contrast agent for magnetic resonance imaging was developed based on ultrasmall superparamagnetic Fe3O4 nanoparticles. The magnetite nanoparticles were synthesized with thermal decomposition method, then loaded on hydrophilic cellulose nanocrystals-poly citric acid… read more here.

DOI: 10.1117/1.jmi.9.1.014003
Abstract: Abstract. Purpose: Dual-contrast protocols are a promising clinical multienergy computed tomography (CT) application for focal liver lesion detection and characterization. One avenue to enable multienergy CT is the introduction of photon-counting detectors (PCD). Although clinical… read more here.
