Real-time radiographic identification of contrast consistency in modified barium swallow studies: An alternative technique

Contrast agents of varying consistency, ranging from thin liquids to solids, are utilized in modified barium swallow (MBS) studies, typically without real-time radiographic labeling. We describe a method for identifying the contrast consistency using radiographic labels during each fluoroscopy sequence. Two cases demonstrating the utility of the radiographic labels in clinical practice are described in detail. Case 1 demonstrates placement of labels prior to each swallowing trial, enabling rapid and accurate identification of the contrast consistency administered. Case 2 demonstrates ambiguities that can occur due to absence of real-time labeling. Our labeling method is an easily implemented and cost-effective technique to promote increased accuracy. Real-time labeling of sequential MBS studies facilitate assessment on sequential studies and for different RIS/PAC systems and will reduce ambiguities and misinterpretations.
