The use of a double contrast technique in the oropharynx and hypopharynx is described and its diagnostic value following treatment is defined. By means of the double contrast pharyngogram, it is possible to demonstrate the pharyngeal mucosa and, post-operatively, the anastomosis. It is the only imaging method which demonstrates the course of swallowing and passage through the pharynx. By paying attention to physiological changes following treatment and taking account of early post-therapeutic appearances, it is possible to form a judgement concerning the peripharyngeal tissue. CT, however, is the method of choice for demonstrating an extraluminal tumour. In view of the ease of the method, double contrast pharyngography is the ideal radiological procedure for close follow-up of patients with malignant tumours of the pharynx.
本文描述了口咽和下咽双对比技术的应用，并明确了其治疗后的诊断价值。通过双对比咽造影，可以显示咽黏膜，术后还能显示吻合口。它是唯一能显示吞咽过程和通过咽部情况的成像方法。通过关注治疗后的生理变化并考虑治疗后早期表现，可以对咽周组织作出判断。然而，CT是显示腔外肿瘤的首选方法。鉴于该方法操作简便，双对比咽造影是对咽恶性肿瘤患者进行密切随访的理想放射学检查方法。
