title: Double contrast cervical esophagography: use of a specially designed cup to aid double-contrast cervical esophagography.
abstract: We designed a cup to aid double-contrast cervical esophagography using photo fluorography and an image intensifier. The cup allows an adequate amount of air to be delivered with the contrast media so that the cervical esophageal lumen expands to give an ideal double contrast image. The clear image is obtained, having to calculate exact timing. The timing sequence we used during the serial radiography was 4 seconds at 2 radiographs per second while the patient continually swallowed the contrast medium and air.
