Two-compartment pharmacokinetic modeling of targeted molecular MRI contrast agents
Introduction Molecular MRI allows the specific detection of biomolecules that are upregulated during disease. To this extent, contrast agents (CAs) are used that home to the targeted biomolecules via high affinity ligands coupled to the CA. Activated endothelial cells in tumor angiogenesis provide well suited disease markers, which are easily accessible for circulating CAs. Several studies have...
متن کاملMolecular imaging with targeted contrast agents.
Molecular imaging with targeted contrast agents by magnetic resonance imaging (MRI) allows for the noninvasive detection and characterization of biological changes on a molecular level. In this article, the principles of molecular MRI and its applications in cardiovascular diseases are reviewed. First, basic properties of positive and negative contrast agents are introduced and their effect on ...
متن کاملGRPR-targeted Protein Contrast Agents for Molecular Imaging of Receptor Expression in Cancers by MRI
Gastrin-releasing peptide receptor (GRPR) is differentially expressed on the surfaces of various diseased cells, including prostate and lung cancer. However, monitoring temporal and spatial expression of GRPR in vivo by clinical MRI is severely hampered by the lack of contrast agents with high relaxivity, targeting capability and tumor penetration. Here, we report the development of a GRPR-targ...
متن کاملBiocompatible Nanocomplexes for Molecular Targeted MRI Contrast Agent
Accurate diagnosis in early stage is vital for the treatment of Hepatocellular carcinoma. The aim of this study was to investigate the potential of poly lactic acid-polyethylene glycol/gadolinium-diethylenetriamine-pentaacetic acid (PLA-PEG/Gd-DTPA) nanocomplexes using as biocompatible molecular magnetic resonance imaging (MRI) contrast agent. The PLA-PEG/Gd-DTPA nanocomplexes were obtained usi...
متن کاملA peptide-targeted MRI contrast agent for cancer molecular imaging
Introduction: Early detection and diagnosis of malignant tumors enable more efficacious cancer treatment at an earlier stage and improvement of cancer patients' survival and quality of the life. Magnetic resonance imaging (MRI) is a powerful imaging modality for cancer detection and diagnosis. However, current clinically used contrast enhanced MRI is not effective for molecular imaging because ...
