Iron Oxide Nanoparticle Based Contrast Agents for Magnetic Resonance Imaging

, 2017
Magnetic iron oxide nanoparticles (MIONs) have attracted enormous attention due to their wide applications, including for magnetic separation, for magnetic hyperthermia, and as contrast agents for magnetic resonance imaging (MRI).

Alignment of contrast enhanced medical images [PDF]

, 2009
The re-alignment of series of medical images in which there are multiple contrast variations is difficult. The reason for this is that the popularmeasures of image similarity used to drive the alignment procedure do not separate the influence of ...

Gadolinium Deposition in Brain: Current Scientific Evidence and Future Perspectives

Frontiers in Molecular Neuroscience, 2018
In the past 4 years, many publications described a concentration-dependent deposition of gadolinium in the brain both in adults and children, seen as high signal intensities in the globus pallidus and dentate nucleus on unenhanced T1-weighted images ...

Low KeV virtual monoenergetic images for detecting low dose iodine- or alternative Gd-based IV contrast agents

Heliyon
Background: The recent shortage of iodine-based intravenous contrast and its cost highlight the need for limiting dose and alterative agents. Purpose: To quantify radiodensity (Hounsfield Units, HU) improvement and potential iodine dose reduction with ...

Gadolinium oxide nanocrystal-based autofluorescent composite nanoparticles as T1-weighted contrast agents for early diagnosis of cancer

, 2013
Early diagnosis of cancer greatly increases the chances of a radical resection. The sensitivity of magnetic resonance imaging (MRI) techniques for detecting early tumor can be increased with the assistance of a positive MRI contrast agent.

Ligand design strategies to increase stability of gadolinium-based magnetic resonance imaging contrast agents

Nature Communications, 2019
Gadolinium(III) complexes are strong enhancers of magnetic resonance imaging (MRI) signals, thus are widely used as contrast agents despite their potential toxicity. Here, the authors review ligand design approaches aimed at improving the stability of Gd(
