In which imaging view is an opaque foreign body visualized in the proximal portion of the esophagus?

The soft tissue neck view is particularly effective for visualizing the proximal portion of the esophagus. This imaging view allows for a clear assessment of the structures in the neck, including the esophagus, trachea, and major blood vessels. When an opaque foreign body is present in the proximal esophagus, it stands out on this view due to the contrast it creates against the surrounding soft tissues, making it easier for healthcare providers to identify and locate the foreign body.

While other views such as the lateral chest or posteroanterior chest may provide some information about the esophagus and surrounding areas, they are less targeted for the specific assessment of the upper esophagus located within the neck. The lateral cervical spine view focuses more on the vertebral column rather than soft tissue structures, which further limits its utility in detecting an opaque foreign body in the esophagus. Therefore, the soft tissue neck view is the most appropriate choice for visualizing an opaque foreign body in this area.
