The oesophagus is generally normal on routine survey radiographs. Signs of aspiration pneumonia may be seen in ventral lung lobes. It can be better differentiated using barium-contrast studies which may show:

To better diagnose oesophagitis, endoscopy with biopsies can be used. Severe oesophagitis will be seen with an oedematous mucosa that is hyperaemic, ulcerated and actively bleeding, whilst less severe cases may require several mucosal biopsies to diagnose the condition.
