Contrast manufacturer E-Z-EM has introduced Varibar, a family of contrast formulations designed specifically for fluoroscopic examination of the swallowing process. The Westbury, NY-based firm believes the Varibar products will provide consistent, repeatable radiographic results in modified swallowing studies.
The Varibar system provides a range of low-, medium- and high-viscosity barium suspensions to evaluate a patient's ability to swallow liquid and solid materials of differing viscosities and volumes, according to the company. Developed in cooperation with speech-language pathologists at several research universities, each Varibar contrast product has been formulated to mimic real food in both texture and taste, according to Patrice Plourde, global product manager of G.I. contrast at the company.
All three Varibar contrasts -- Varibar Nectar, Varibar Honey and Varibar Pudding -- share low-coating characteristics that leave the esophagus stripped and clean, he said. This facilitates accurate diagnosis and treatment of oropharyngeal dysphagia, Plourde said.
Varibar has a 40% weight-to-volume density, which E-Z-EM claims is ideal for both analog and digital videofluoroscopy systems. Varibar Nectar is provided in unit-dose containers, while Varibar Honey and Pudding are supplied in multidose tubes.

![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&fit=crop&h=112&q=70&w=112)
