Spectral Computed Tomography with a Photon-Counting Silicon-Strip Detector
Computed tomography (CT) is a widely used medical imaging modality. By rotating an x-ray tube and an x-ray detector around the patient, a CT scanner is able to measure the x-ray transmission from all directions and form an image of the patient’s interior. CT scanners in clinical use today all use energy-integrating detectors, which measure the total incident energy for each measurement interval...
متن کاملAntibiofouling polymer-coated gold nanoparticles as a contrast agent for in vivo X-ray computed tomography imaging.
Current computed tomography (CT) contrast agents such as iodine-based compounds have several limitations, including short imaging times due to rapid renal clearance, renal toxicity, and vascular permeation. Here, we describe a new CT contrast agent based on gold nanoparticles (GNPs) that overcomes these limitations. Because gold has a higher atomic number and X-ray absorption coefficient than i...
متن کاملLanthanide nanoparticles as vascular contrast agents for preclinical computed tomography
Introduction: Recent advances in nanotechnology have led to the development of vascular contrast agents for preclinical computed tomography (CT). The advantage of using nanoparticles is the ability to achieve prolonged residence times for preclinical CT, which can take tens of minutes; this is attained by polymer-coated nanoparticles exceeding 10 nm in size. Although long-circulating nanopartic...
متن کاملSynthesized Gd2O3 nanoparticles as contrast agent
Introduction: Gd (III) ion has been known to be the best metal ion in the periodic table that can be used as a T1 MRI contrast agent. Gadolinium have 7 unpaired electrons and these electrons can make magnetic area. No other metal ions possess unpaired electron more than this. CAs based on the element Gd are classified as “positive”, by opposition to “negative” CAs. Nowadays, G...
متن کاملMelanin nanoparticles as a novel contrast agent for optoacoustic tomography
We describe the synthesis and characterization of melanin-like nanoparticles (MNP) as novel contrast agents for optoacoustic tomography. Good dispersion stability of high concentration MNPs in different biological media was achieved with thiol-terminated methoxy-poly(ethylene glycol), which can be used for further functional conjugation. MNP-PEG were found biocompatible with human MCF-7 and 3T3...
