Gold as a Potential Contrast Agent for Dual-Energy CT

Milk shows potential as CT contrast agent.

of these two bacteria may influence weight, the researchers performed biochemical and genomic analyses of the gut microbes in obese and lean mice. They found that the microbial genomes of the bacteria found in obese mice were rich in genes encoding enzymes that break down otherwise indigestible food. “Our results indicate that the obese microbiome has an increased capacity to harvest energy fro...

Investigation of acoustic properties of silica coated gold nanoparticle as contrast agent for Ultrasonography

Interoduction: Ultrasound images have often low contrast due to small differences in acoustic impedance between different tissues. Air or gas microbubbles that surrounded by membrane are most of the contrast agents in ultrasound imaging. Problems such as instability in sound pressure and inability in penetrating from the blood vessel into body tissues limited the use of microbubbles into the in...

Antibiofouling Polymer Coated Gold@Iron Oxide Nanoparticle (GION) as a Dual Contrast Agent for CT and MRI

Dual Energy CT Imaging for Suspected Pulmonary Embolism Using a Lower Dose of Contrast Agent

CT is the preferred imaging modality to diagnose pulmonary embolism Evaluation of pulmonary embolism with dual energy CT (DECT) retains diagnostic accuracy using less contrast material than standard CT Virtual monochromatic images, derived from DECT data, show contrast material at greater intensity than standard CT Iodine images show the distribution of contrast material and can be used to asse...

Hydrothermal Synthesis of an Ethiodol Based Ferrofluid as a Potential MRI Contrast Agent

In the present work, stable ferrofluids containing oleic acid capped magnetite nanoparticles were synthesized via low temperature hydrothermal method. The physical and chemical properties of the synthesized particles were studied using TEM, XRD, AFM, VSM and PCS techniques. Mean particles size of the samples was between 4.5 and 10 nanometers, depending on experimental conditions. Effect ...
