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 کاملDendrimer-entrapped gold nanoparticles as potential CT contrast agents for blood pool imaging
The purpose of this study was to evaluate dendrimer-entrapped gold nanoparticles [Au DENPs] as a molecular imaging [MI] probe for computed tomography [CT]. Au DENPs were prepared by complexing AuCl4- ions with amine-terminated generation 5 poly(amidoamine) [G5.NH2] dendrimers. Resulting particles were sized using transmission electron microscopy. Serial dilutions (0.001 to 0.1 M) of either Au D...
متن کاملHigh-spatial-resolution multistation MR angiography with parallel imaging and blood pool contrast agent: initial experience.
The purpose of this study was to prospectively evaluate the diagnostic accuracy of reader detection of 75% or greater stenosis at high-spatial-resolution multistation magnetic resonance (MR) angiography performed with matrix coils and a blood pool contrast agent. Ten healthy volunteers and 10 patients were examined. All participants provided informed consent to participate in this institutional...
متن کاملUltra High-Resolution In vivo Computed Tomography Imaging of Mouse Cerebrovasculature Using a Long Circulating Blood Pool Contrast Agent
Abnormalities in the cerebrovascular system play a central role in many neurologic diseases. The on-going expansion of rodent models of human cerebrovascular diseases and the need to use these models to understand disease progression and treatment has amplified the need for reproducible non-invasive imaging methods for high-resolution visualization of the complete cerebral vasculature. In this ...
متن کاملLanthanide nanoparticles as vascular contrast agents for micro - CT
Introduction Vascular development is extensively studied in small animals. Micro-CT is routinely used to study the vasculature and it requires a high-attenuating contrast agent to remain in the blood pool during in vivo imaging (i.e. tens of minutes). This can be achieved by using polymer-encapsulated nanoparticles exceeding 10 nm in diameter. Although nanoparticle agents exist for micro-CT, th...
