GE Healthcare of Chalfont St. Giles, U.K., said that a head-to-head taste test of oral contrast agents found a significantly greater preference for its Omnipaque agent (iohexol) compared to Covidien's Gastroview (diluted diatrizoate sodium).
The study, published in the November issue of the American Journal of Roentgenology, also found no significant differences between the agents in terms of side effects or bowel opacification, according to lead author Michelle McNamara, MD, of the University of Alabama at Birmingham.
The prospective, double-blind study included 300 adult patients.

![Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD). Top row: Images in a 68-year-old male patient with higher 10-year mean ambient air pollution exposure (7.9 μg/m3 for particulate matter measuring ≤2.5 μm in diameter [PM2.5] and 17.4 parts per billion [ppb] for NO2) with extensive CAD (coronary artery calcium score [CACS] >1,000 and obstructive CAD [≥70% diameter stenosis]). Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
