Iodixanol is an iso-osmolar non-ionic dimeric hydrophilic contrast agent with a higher viscosity than the monomeric agents. It is the only Food and Drug Administration (FDA)-approved iso-osmolar agent in the United States, and it is the only contrast ...

Migration of Active Rings in Porous Media [PDF]
Inspired by how the shape deformations in active organisms help them to migrate through disordered porous environments, we simulate active ring polymers in two-dimensional random porous media. Flexible and inextensible active ring polymers navigate smoothly through the disordered media.

Bloch Waves in Crystals and Periodic High Contrast Media [PDF]
Analytic representation formulas and power series are developed describing the band structure inside periodic photonic and acoustic crystals made from high contrast inclusions. Central to this approach is the identification and utilization of a resonance

Influence of contrast media dose and osmolality on the diagnostic performance of contrast fractional flow reserve [PDF]
Background—Contrast fractional flow reserve (cFFR) is a method for assessing functional significance of coronary stenoses, which is more accurate than resting indices and does not require adenosine.

Invariant imbedding theory of wave propagation in arbitrarily inhomogeneous stratified bi-isotropic media [PDF]
Bi-isotropic media, which include isotropic chiral media and Tellegen media as special cases, are the most general form of linear isotropic media where the electric displacement and the magnetic induction are related to both the electric field and the magnetic intensity.

Contrast-induced nephropathy: a review of literature [PDF]
Today, radiological procedures using intravascular iodinated contrast media are being widely used for the diagnoses and treatment of various diseases, which highlight one of the main etiologies of contrast-induced nephropathy and hospital-acquired renal ...

Plants used to decrease serum creatinine levels and contrast-induced nephropathy: A review article [PDF]
:Background and aims: Contrast-induced nephropathy (CIN) is one of the most common reasons for acute kidney failure. Because of the increasing use of contrasts for computed tomography and angiography and coronary interventions, the incidence of CIN is on

Contrast-induced nephropathy (CIN) - epidemiology, risk factors and prevention
Introduction: Contrast-induced nephropathy is one of the most serious adverse effects of radiocontrast agents usage. It is currently listed in the literature as the third most common cause of iatrogenic acute kidney injury.

Selection of contrast media [PDF]
The pathophysiologic mechanisms of contrast-induced nephropathy (CIN) have been reviewed by Persson and Tepel. They focus on the renal response to contrast media (CM). In this section, we focus on the CM itself. Aspects of importance with regard to CIN include the route of administration, the volume of CM, the manner of X-ray attenuation, and the ...
