Mesoporous Silica Nanoparticles with Co-Condensed Gadolinium Chelates for Multimodal Imaging

open access: yesNanomaterials, 2011
Several mesoporous silica nanoparticle (MSN) contrast agents have been synthesized using a co-condensation method to incorporate two different Gd3+ complexes at very high loadings (15.5–28.8 wt %).

Electrospun Contrast Agent-Loaded Fibers for Colon-Targeted MRI [PDF]

open access: yes, 2016
Magnetic resonance imaging is a diagnostic tool used for detecting abnormal organs and tissues, often using Gd(III) complexes as contrast-enhancing agents. In this work, core-shell polymer fibers have been prepared using coaxial electrospinning, with the

Improved efficiency and diagnostic utility of inpatient transthoracic echocardiography following implementation of a sonographer-initiated perflutren-based contrast administration protocol

open access: yesCardiovascular Ultrasound, 2020
Background Up to 20% of resting echocardiograms obtained are suboptimal leading to further downstream testing and delays in diagnosis. Contrast enhanced echocardiography is well established and endorsed for use by the American Society of Echocardiography

Contrast Agents [PDF]

open access: yesCurrent Protocols in Magnetic Resonance Imaging, 2002
AbstractContrast agents in general are exogeneous substances employed to alter natural tissue contrast. The motivation behind the use of contrast agents in MR imaging is to further enhance contrast between normal and diseased tissue types and indicate functionality of an organ.

Manganese ferrite nanocubes as an MRI contrast agent

open access: yesMaterials Research Express, 2020
Facile synthesis of superparamagnetic, highly crystalline, manganese ferrite nanocubes (MnNCs) is reported. X-ray diffraction depicts single-phase face-centred cubic spinel and the electron microscopy represents the nearly monodispersed cube-like ...
