Gd-DTPA-based MR-visible polymer for direct visualization of interventional devices.

چکیده
We developed a Gd-DTPA (gadolinium(III)-diethylenetriaminepentaacetic acid)-based coating copolymer of hydrophilic and hydrophobic subunits to obtain visibility, hydrophilicity, and durability for passive visualization of catheters used in MR-guided interventions. We then examined a metal-free catheter coated with the polymer in a phantom and in porcine brain tissue ex vivo. Successful visualization of the coated device demonstrated the applicability of the new coating technique for visualizing catheters used in MR-guided interventions.

High-resolution vascular imaging of the rat spine using liposomal blood pool MR agent.
BACKGROUND AND PURPOSE High-resolution, vascular MR imaging of the spine region in small animals poses several challenges. The small anatomic features, extravascular diffusion, and low signal-to-noise ratio limit the use of conventional contrast agents. We hypothesize that a long-circulating, intravascular liposomal-encapsulated MR contrast agent (liposomal-Gd) would facilitate visualization of...
متن کامل3D MRI-guided Passive Catheter Tracking and Visualization using HYPR-based Techniques
INTRODUCTION Catheter tracking and visualization require both good spatial and temporal resolution. Achieving simultaneously both high temporal and spatial resolution is extremely difficult with current methods that use Cartesian k-space acquisition employing phase encoding. To date, passive device tracking and visualization techniques have typically been limited to two dimensions [1-2]. This i...
متن کاملPreparation of polymer-based magnetic resonance imaging contrast agent to visualize therapeutic angiogenesis.
The objective of this study was to design and prepare a new contrast agent of magnetic resonance (MR) imaging for the evaluation of therapeutic angiogenesis. Diethylenetriaminepentaacetic acid (DTPA) residue of a chelator was chemically introduced to dextran with a molecular weight of 74,000 (dextran-DTPA). Cyclic peptide containing an arginine-glycine-aspartic acid (RGD) sequence (cyclic RGD) ...
متن کاملDevelopment of Bifunctional Gadolinium-Labeled Superparamagnetic Nanoparticles (Gd-MnMEIO) for In Vivo MR Imaging of the Liver in an Animal Model.
Liver tumors are common and imaging methods, particularly magnetic resonance imaging (MRI), play an important role in their non-invasive diagnosis. Previous studies have shown that detection of liver tumors can be improved by injection of two different MR contrast agents. Here, we developed a new contrast agent, Gd-manganese-doped magnetism-engineered iron oxide (Gd-MnMEIO), with enhancement ef...
