Introduction: All of the Imaging modalities have advantages and disadvantages alone. So if we want to have the best and perfect image, combining these modalities produces something we desired. PET-MR images consist of morphologic and metabolic data. MRI and PET provide high spatial and contrast resolution and high sensitivity and molecular information respectively. Hybrid PET-...

magnetic resonance imaging (mri) contrast agents most commonly agents used in diagnosing different diseases. several agents have been ever introduced with different peculiar characteristics. they vary in potency, adverse reaction and other specification, so it is important to select the proper agent in different situations. we conducted a systematic literature search in medline/pubmed, web of s...

objective(s): the aim of this work was to prepare and characterize magnetic nanoparticles (mnps) as theranostic system to act simultaneously as drug carrier and mri contrast agent. chitosan-coated mnps (cmnps) were prepared and loaded with silymarin. silymarin-loaded cmnps were characterized with various techniques and their potential as mri contrast agent was also evaluated. materials and meth...

Background: The monoclonal antibody, C595, against breast cancer cell line was conjugated with cyclic anhydride gadolinium-diethylenetriaminepenta-acetic acid (Gd-cDTPAa) to produce Gd-DTPA-C595 and used as specific breast cancer cell line (MCF-7) contrast agents in magnetic resonance imaging (MRI).  Methods: After incubation of breast cancer cell line (MCF-7), with different contrast agents (G...
