EGG vs. Barium Esophogram or Modified Barium Swallow?

Quinn describes a progressively worsening sensation of solid food getting stuck around her sternal notch. Symptoms do improve whenever she drinks liquids. They did not change when she was started on a PPI trial three months prior to the current appointment. So thinking about what we now know about Quinn and her history, how would you determine what the next best step for evaluating Quinn's dysphagia would be? And within that, which patients should be evaluated within EGG versus barium esophogram or a modified barium swallow?
