Hypersensitivity to Gadolinium-Based Contrast Media
Frontiers in Allergy, 2022 Gadolinium-based contrast agents (GBCAs) are frequently used in magnetic resonance imaging (MRI) examinations to increase sensitivity in diagnoses. Recently, an increase in the description of hypersensitivity reactions to GBCAs has been detected.

Tackling the increasing contamination of the water supply by iodinated contrast media
Insights into Imaging, 2022 Contrast media are essential for diagnostic and interventional procedures. Iodinated contrast media are the most commonly used agents, with CT requiring the largest overall quantities.

Motion of discrete interfaces in low-contrast periodic media [PDF]
Netw. Heterog. Media 9 (2014) 169-189, 2014 We study the motion of discrete interfaces driven by ferromagnetic interactions in a two-dimensional low-contrast periodic environment, by coupling the minimizing movements approach by Almgren, Taylor and Wang and a discrete-to-continuum analysis. As in a recent paper by Braides and Scilla dealing with high-contrast periodic media, we give an example ...

Waiting times between examinations with intravascularly administered contrast media: a review of contrast media pharmacokinetics and updated ESUR Contrast Media Safety Committee guidelines. [PDF]
Eur RadiolThe pharmacokinetics of contrast media (CM) will determine how long safe waiting intervals between successive CT or MRI examinations should be. The Contrast Media Safety Committee has reviewed the data on pharmacokinetics of contrast media to suggest ...

Transport properties of heterogeneous materials derived from Gaussian random fields: Bounds and Simulation [PDF]
Phys. Rev. E Vol 51(5) pages 4141-4154 (1995), 2000 We investigate the effective conductivity ($\sigma_e$) of a class of amorphous media defined by the level-cut of a Gaussian random field. The three point solid-solid correlation function is derived and utilised in the evaluation of the Beran-Milton bounds.

Head-Neck Dual-energy CT Contrast Media Reduction Using Diffusion Models [PDF]
arXiv, 2023 Iodinated contrast media is essential for dual-energy computed tomography (DECT) angiography. Previous studies show that iodinated contrast media may cause side effects, and the interruption of the supply chain in 2022 led to a severe contrast media shortage in the US.

Super-resolution in high contrast media [PDF]
Proceedings of the Royal Society A, 2014 A mathematical theory is developed to explain the super-resolution and super-focusing in high contrast media. The approach is based on the resonance expansion of the Green function associated with the medium. It is shown that the super-resolution is due to sub-wavelength resonant modes excited in the medium which can propagate into the far-field.
