Sponsor's own description
In traditional video-fluoroscopic-swallowing study, a lipid-soluble contrast (barium sulfate) has been used more than 30 years. However, it can cause chemical pneumonitis and subsequently impair reliability of video-fluoroscopic-swallowing study if aspirated. The authors reviewed the safety and usefulness of an water soluble agent-based swallowing test.
