Read more Background RADIOLOGICAL TECHNIQUEThe esophagogram is based on the acquisition of multiple sequential images of the esophagus after the ingestion of effervescent powders and barium contrast.PATIENT POSITIONINGDuring the swallowing assessment, a lateral projection along with an anteroposterior (AP) projection, are acquired. Perform left posterior oblique projections in the supine position, where the patient holds a cup with a straw in their left hand (Fig 1). [fig 1] To visualize the entry of contrast into the gastric chamber, use a supine/anterior right oblique projection (Fig...
Read more Findings and procedure details ANATOMYThe esophagus is a tubular structure measuring 20–24 cm in length, extending from the pharynx to the stomach.The structures detected in an esophageal study are: Upper esophageal sphincter: Represents the pharyngoesophageal junction and is formed by the cricopharyngeal muscle. Lower esophageal sphincter, phrenic ampulla, or esophageal vestibule: Located between the A and B rings. (Fig 3). [fig 3] The barium esophagogram permits the visualization of the longitudinal, thin and uniform folds of the esophagus. Occasionally, transient transverse folds, primarily located in the middle and distal...
Read more Conclusion The esophagogram is a valuable technique for the functional and morphological examination of the esophagus. With the focus on CT and MR in modern training, there is a growing gap in knowledge regarding the execution and interpretation of barium esophagram studies. Consequently, as radiologists, it is crucial to adequately train residents in this technique
