Central effects of iohexol and iopamidol, non-ionic contrast media.

Ionic or non-ionic contrast media in stent placement.

In his letter to the editor, Dr Schräder poses the rhetorical question of whether the results of our study are ‘true’. To substantiate his doubts, he points out that different non-ionic contrast media (CM) were used in our study and calls for a subgroup analysis. In addition, he refers to the data obtained during the COURT trial. I am very happy to be given this opportunity to discuss the inter...

A comparison of iopamidol and iohexol in cerebral angiography.

Iopamidol and iohexol, the new nonionic low-osmolality contrast agents, have both been shown to be safe, effective, and better tolerated than conventional ionic agents for cerebral angiography. In this randomized, double-blind study involving 40 patients, these two agents were compared for adverse effects, radiographic quality, and patient tolerance. No significant differences were observed in ...

Comparison of ionic, monomer, high osmolar contrast media with non-ionic, dimer, iso-osmolar contrast media in ERCP.

OBJECTIVE Pancreatitis is the most common and serious complication of endoscopic retrograde cholangiopancreatography (ERCP). Several studies have compared contrast media (CM) with different osmolalities, but the results are conflicting. We conducted this study to clarify the difference between 2 CM used in ERCP. METHODS Five hundred and seventy-six patients were examined by using ERCP in our ...

Do Non-Ionic Contrast Media Temporarily Improve Corneal Transparency?

Dear Editor, Phacoemulsification in eyes with scarred corneas is challenging and due to the poor surgical view, carries an increased risk of complications. 1 In healthy eyes, the cornea is transparent due to the small diameter, and relatively regular size and spacing of stromal collagen fibrils, in addition to similarity of the refractive indices of collagen fibrils (1.411) and the extrafibrill...
