OBJECTIVES To assess the impact of combining low-tube voltage acquisition with iterative reconstruction (IR) techniques on the iodine dose in coronary CTA. METHODS Three minipigs underwent CCTA to compare a standard of care protocol with two alternative study protocols combining low-tube voltage and low iodine dose with IR. Image quality was evaluated objectively by the CT value, signal-to-no...

acute renal failure is one of the side effects while using intravenous immunoglobulins. this complication is also observed with iodinated contrast media. herein, we describe a patient with acute renal failure who received intravenous immunoglobulins and iodinated contrast media concomitantly. both drugs are responsible for osmotic nephrosis. the same effect on renal cells may explain a synergis...

Iodinated contrast media (CM) are the most commonly used injectables in radiology today. A range of different media are commercially available, combining various physical and chemical characteristics (ionic state, osmolality, viscosity) and thus exhibiting distinct in vivo behaviour and safety profiles. In this paper, numerical simulations of blood flow with contrast media were conducted to inv...

Iopamidol, a nonionic, water-soluble contrast medium, has been recently recommended for myelography. As with other such media, the extent of parenchymal penetration is of interest in relation to the genesis of clinical complications. In this study the degree and depth of brain penetration of intrathecal iopamidol, using an iodine concentration of 280 mg l/ml, were compared at 15 and 60 min in a...

This study evaluated the impact of contrast material on the estimation of absorbed dose due to computed tomography pulmonary angiography (CTPA) using the ICRP reference phantoms. To address this issue, we modified the previously developed physiologically based pharmacokinetic (PBPK) model to be conformed to the ICRP reference phantoms. Regarding the standard contrast material injection protocol...

150 microg iodine are daily required for thyroid hormone synthesis. The thyroid gland has intrinsic mechanisms that maintain normal thyroid function even in the presence of iodine excess. Large quantities of iodide are present in drugs, antiseptics, contrast media and food preservatives. Iodine induced hyperthyroidism is frequently observed in patients affected by euthyroid iodine deficient goi...

The Swedish radiologist Torsten Almén is the first clinical radiologist ever to have made a fundamental contribution to intravascular contrast medium design, the development of non-ionic contrast media. He became emotionally triggered by the patients' severe pain each time he injected the ionic "high-osmolar" contrast media when performing peripheral arteriographies in the early 1960s. One day ...

conclusions contrast-agent-induced nephropathic changes are more closely related to the magnitude of lipid peroxidation than protein oxidation. results compared with the control group, groups cin and n + cin had significantly higher urea and lhp levels (p < 0.05 and p < 0.001, respectively) and significantly lower cu, zn-sod activity and creatinine clearance (p < 0.05). there was no statistical...
