[Dysphagia] Food and barium

[smhjr at surfbest.net (smhjr@surfbest.net)]

How do the new EZ Em negatively charged (will not adhere to because
it has a negative charge)barium viscosities simulate what would
happen with food/liquid? By giving it a negative charge it has a
major impact on swallow studies.....and not for the better.
