Preparation of Chitosan-coated Magnetite Nanoparticles by Sonochemical Method for MRI Contrast Agent
AIM We wanted to explore if whole-body magnetic resonance imaging (MRI) including diffusion-weighted (DW) and liver-specific contrast agent-enhanced imaging could be valuable in lesion detection of neuroendocrine tumors (NET). [11C]-5-Hydroxytryptophan positron emission tomography/computed tomography (5-HTP PET/CT) was used for comparison. MATERIALS AND METHODS Twenty-one patients with NET we...
The application of magnetic resonance imaging (MRI) to non-invasively assess disease biomarkers has been hampered by lack of desired contrast agents with high relaxivity, targeting capability, and optimized pharmacokinetics. We developed a novel MRI probe which targets HER2, a biomarker for various cancers and a target for anti-cancer therapies. This multimodal HER2-targeted MRI probe integrate...
Magnetic resonance imaging (MRI) is a widely used biomedical imaging modality that derives much of its contrast from microscale magnetic field gradients in biological tissues. However, the connection between these sub-voxel field patterns and MRI contrast has not been studied experimentally. Here, we describe a new method to map subcellular magnetic fields in mammalian cells and tissues using n...
