Gold nanoparticles: a new X-ray contrast agent.
There have been few fundamental improvements in clinical X-ray contrast agents in more than 25 years, and the chemical platform of tri-iodobenzene has not changed. Current agents impose serious limitations on medical imaging: short imaging times, the need for catheterization in many cases, occasional renal toxicity, and poor contrast in large patients. This report is the first demonstration tha...
متن کاملSynthesized Gd2O3 nanoparticles as contrast agent
Introduction: Gd (III) ion has been known to be the best metal ion in the periodic table that can be used as a T1 MRI contrast agent. Gadolinium have 7 unpaired electrons and these electrons can make magnetic area. No other metal ions possess unpaired electron more than this. CAs based on the element Gd are classified as “positive”, by opposition to “negative” CAs. Nowadays, G...
متن کاملPreparation of functionalized gold nanoparticles as a targeted X-ray contrast agent for damaged bone tissue.
Conventional methods used to image and quantify microdamage in bone tissue are limited to thin histological sections. Therefore recent studies have begun to investigate methods for non-destructive, three-dimensional (3-D) detection and imaging of microdamage in bone tissue. The objective of this study was to investigate gold nanoparticles (Au NPs) as a potential damage-specific X-ray contrast a...
متن کاملBisphosphonate-functionalized Gold Nanoparticles as a Targeted X-ray Contrast Agent for Breast Microcalcifications
by Lisa E. Cole Breast cancer is the most common cancer and the second leading cause of cancerrelated deaths among women. Early detection is considered the best option for reducing morbidity and mammography is the current gold standard for early detection of breast cancer. Microcalcifications are the most common abnormality observed on a mammogram and are early markers for breast cancer. Howeve...
متن کاملDextran-encapsulated barium sulfate nanoparticles prepared for aqueous dispersion as an X-ray contrast agent
Barium sulfate (BaSO4) nanoparticles (\100 nm) are of interest to provide improved performance over microscale BaSO4 particles, which are currently used clinically as an X-ray contrast agent or radiopacifier, and to further enable passive or targeted delivery of BaSO4 contrast agents. The stability of BaSO4 nanoparticle dispersions in aqueous media is critical for these uses but has received li...
