Popa Nita et al. 2013. Matching the rheological properties of videofluoroscopic contrast agents and thickened liquid prescriptions

This study assesses the feasibility of thickening video fluoroscopic contrast agents for dysphagia, including using a xantham gum-based thickener. The results showed that for optimal patient outcomes, only diagnostic materials and thickening agents for which reliable viscosity data are available should be used.
