- monitors
- Contrast: Polibar (barium)
- face cloth - no prep is neccessary
- drink chalky barium sulfate mixture to sufficiently coat the walls of the esophagus
- visualizes intrinsic lesions and extrinsic pathology on esophagus
- normal structures indent the esophagus: aortic arch, left main stem bronchus and left atrium
- 80 kV, 250 mAs
- exposure time of 0.1 sec or less for upright
- barium passes slowly through esophagus at end of full inspiration
- barium passes quicker if swallowed at end of moderate inspiration
- respiration delayed a couple seconds after swallowing FT: 8 seconds
DAP: 273.2 micGym2 Zenkers Diverticulum Radiologist Report - level of C6
